We Don't Need No Stinkin' Backsaws#

There is great debate among the Saw Nerds (I'm a card-carrying member) about when the backsaw came into this world, kicking and screaming and whipping its lamb's tongue to and fro.

Historic documents have been read. Great thoughts have been thinked. The Internet was clicked many times.

But what gets little attention is actually why the backsaw was ever developed.

In the mind of veteran carpenter and tool collector Carl Bilderback, you don't need a backsaw.

"You can cut any joint you want with a 16" panel saw," he said. "It's more than stiff enough for the job. So why do we have backsaws?"

Bilderback didn't have the answer to that rhetorical questions, but he did offer up some other thoughts. The late Cecil Pierce cut his dovetails (beautifully by the way) with a hacksaw. You can read all about that in his short book "The Precision Handcutting of Dovetails" from Astragal Press. And the book "Modern Practical Joinery" by George Ellis shows experienced joiners cutting tenons with handsaws. "Look ma, no back."

"Why do we even have $200 dovetail saws to do something you can do with a $15 hacksaw from Ace Hardware?" Bilderback asks.

Bilderback has cut lots of joints with a panel saw and recommends that if you want to try it yourself that you use a saw with little or no set.

This afternoon I gave it a try and cut dovetails with a crosscut panel saw. I was laughing the whole time I did it because it was extremely easy to switch from a backsaw to a panel saw. The tool leaves a big kerf in its wake, but that actually made it easy for the coping saw to drop in there to remove the waste.

Sawing and 'the Fumes of the Stomach'#

One of the best things about working on this new book, "The Joiner and Cabinet Maker," has been the opportunity to poke through some 19th-century books on the trades. I always disliked history class in high school and college, but this stuff fascinates me to no end.

Recently I dug up some descriptions of the 19th-century trades in a huge book that was intended to be a guide for parents and children who were trying to choose a profession. Most of the entries from this 1842 book describe each job in a somewhat glamorous fashion. How you have to be strong and ingenious to be a carpenter or joiner. Or how you have to be excellent at drawing to become a cabinet maker.

But the description of the profession of "Sawyer" cracked me up. Perhaps I've just been buried too long in this sort of material, but I found this one a real knee-slapper. The author begins by saying that many sawyers would tend to work for many masters.

"(T)hey either find 'nothing stirring,' and literally starve awhile, or make such astonishing sums at piece work, as to set their heads a madding with the fumes of the stomach; they become broilsome, drink unaccountably, fight any body or thing, pawn their tools by scores, and, when Tuesday comes round, find themselves under the necessity of kicking the master for an advance."

"Who would be a Sawyer? Or, being one, would not work out his own reformation in time?"

— from "The Complete Book of Trades" by Nathaniel Whittock (1842 edition), page 398

Sounds like fun. Sign me up.

Little Teeth Filed for… Who Cares?#

Recently, a woodworking colleague suggested to me that saw teeth designed for crosscutting are an invention of modern marketing.

Early saws, he suggested, we’re probably filed for basically a rip cut. But because the teeth were hand filed, they probably had a little fleam, which made them cut more smoothly than a pure rip tooth with no fleam.

It’s an interesting argument that has no real answer – until we find the DNA of an 18th-century saw filer encased in some amber and decide to open a theme park on a deserted tropical island (sign me up).

Other woodworking authorities I trust have suggested that saw filing patterns were actually more complex in the 18th century than they are today. In other words, we are the primitives.

All I know is that they can take away my Zona Razor Saw from my cold, dead hands. Or they can take it when it’s kinked – whichever comes first.

The Zona Razor Saw is a marvel of modern manufacturing. Made in the USA for the price of 2.5 chai lattes, it’s a 24 tpi backsaw with a .01”-thick sawplate that cuts on the pull stroke. I use this $11 saw for almost everything. Rips. Crosscuts. Miters. Whatever.

The magic of the saw is not in the fact that it’s filed for a rip cut, but that it has 24 tpi. Once you get to teeth that small, it really doesn’t matter so much how they are filed. This saw leaves glass-smooth surfaces when it rips and crosscuts. It tracks beautifully. It is comfortable and balanced.

But before you think it also is going to mow your lawn, paint your house and raise your kids to be truthful and wise, it know that it has a fatal flaw. The sawplate is easily kinked. I’ve had one since 2006, and I have been using it on every project. The cherry-red-dyed handle has faded to pink, and the sawplate has a subtle wave to it.

It still tracks fairly straight – straight enough for most joinery. But this weekend I decided to try to fix the plate. I bent it this way and that with my fingers. I tapped it with a hammer on an anvil. I tweaked it with pliers. And eventually I buckled under and ordered another one from Lee Valley Tools.

If you haven’t tried the Zona Razor Saw, I highly recommend you get one for your tool kit.

By the way, the vast and insidious Zona model-making consortium did not pay for this blog entry. Just so you know.

I’ve Seen the History of Saws#

This week I had an unusual visitor in the office. Auctioneer Toot Ewalt loaned me the rare 18th-century dovetail saw that he brought to the Woodworking in America conference earlier this month. I had the saw sitting on my desk for 10 days along with all the other dovetail saws we own.

(If you haven’t heard the wild story about this circa 1770 saw made by John Kenyon, check out my blog entry at Woodworking Magazine.)

Between frantic bouts of editing manuscripts for the February 2009 issue of Popular Woodworking I picked up each saw over and over to get a feel for the differences in the handles. After 10 days I concluded that the Kenyon saw was as comfortable as the saw I’ve picked as my daily driver: the Lie-Nielsen Independence dovetail saw.

That’s good news because Mike Wenzloff at Wenzloff & Sons is building a reproduction of this saw. And if a reproduction isn’t good enough for you, then start watching the action catalogs. The saw’s owner says he’s investigating selling the original saw at auction.

If you haven’t noticed by now, saw and handplane handles are important to me. If the tool isn’t comfortable, it will be difficult to use. Now, as woodworkers, we have the tools to make our own handles. But have you ever tried?

I sure have. I’ve made several saw handles and plane totes during the last decade, and I’ve never been happy with my efforts. I’ve also taken a rasp to a few other handles with mixed results. My tendency is to make the curves too pronounced. And to reduce the handle’s width too much.

I’ve found that handles are much like the seat of a Windsor chair. When I make a seat that is really sculpted, it feels good when I first sit in it. But I quickly get tired of sitting in highly sculpted chairs. My most comfortable chairs have shallow saddles. (Correction: My most comfortable chairs have cushions.)

Same goes for handles. The overly sculptural ones aren’t comfortable after I cut a few joints. But dialing in the right amount of shaping has been a challenge for me. Hence, my obsession with finding saws with good stock handles.

However, if you want to try to make your own handle, then download this tracing supplied to Lost Art Press by woodworker William Duffield.

Real Details
The other revelation about the Kenyon saw was its level of fit and finish. It wouldn’t pass muster in a modern shop. Heck, Mike Wenzloff would probably throw this handle on the burn pile. You can still see rasp marks all over the tote that look original (the saw shows no sign of being refinished). The slot for the blade is overcut – a no-no in modern work.

And yet this is the prettiest saw I have ever held. I even like the cringe-inducing hang hole.

My only regret during my 10-day affair with this saw is that I didn’t get to cut a dovetail with its 20 (or perhaps 21) ppi blade. The teeth are in poor shape, the blade has dropped, the handle is loose and the sawplate is significantly bent.

I guess I’m going to have to wait for Wenzloff to finish up his reproductions before I can experience the whole package. He promised that I can borrow one of his Kenyon saws (I thought about buying one, but I need another dovetail saw like I need another smoothing plane). When I get the Wenzloff saw in hand, I’ll file a full report.

Tenon Saws: Learning About Leaning#

Though I liked high school as much as a three-year-long colonoscopy, there are sometimes when it takes a high school teacher to teach you something.

In this case, it was a high school physics teacher who taught me an important lesson about tenon saws. Here’s the story.

For the last few years, I’ve been trying to explain to people how a freakishly huge tenon saw is actually easier to balance on your work (no matter what the size of your work) than a smaller tenon saw or sash saw.

“It’s the higher center of gravity,” I implored to a room full of blank stares. “It’s higher – that gravity thing – so it’s… easier. You know?”


This is a truth I know in my gut. The Wenzloff & Sons Kenyon-style tenon saw I’ve been using for the last couple years is a breeze to balance. This is despite the fact that the blade is 19” long and it feels like there is almost 6” of blade under the huge and heavy brass back. When you see this saw, your first instinct is to think: That saw is going to tip and stagger like Gunsmoke’s “Festus.”

But once you try this saw, you think differently.

But try explaining that to people. After my feeble attempt, a high school physics teacher jumped into the conversation. He said this is easy to explain: Try balancing a broom up in the air on a few fingers. If you have the bristles on your hand, it’s harder to balance the broom than if you have the bristles in the air.

This, he explained, is why the big tenon saw is easier to balance in the air. Having the weight up in the air makes it easier for you to sense if the saw is out of balance and to make corrections. This, I concluded, is a brilliant explanation.

Back in our shop in Cincinnati I tried this experiment with our shop broom. It really was easier to balance it with the bristles in the air.

So I used this analogy last weekend to explain the tenon saw to a group of 40 or so woodworkers. To demonstrate, I looked around for a broom. No luck. So I picked up my Warrington hammer to show them how this works.

First I put the hammer head in my palm and showed how shaky it was. Then I balanced it with the head in the air. And my precious and very early Warrington hammer plunged to the concrete floor.

Dang. I still dislike school.
