Dovetail Chisels, Something New and Interesting (Chisels are sold)




As a lot of you know I've been on somewhat of a hiatus from Tool making.  It's been refreshing to pursue other types of work and it renews the spirit of creativity. I have made some tools along the way but mainly for my own needs.

I built what I would consider my dream shop for a someone else last year. It was a major construction undertaking that I wasn't sure I could accomplish. As in a lot of situations you find that you're capable of a lot more than you can imagine. For quite a while we could work at our leisure and then cover everything from the elements. We did this thru putting in the foundation, framing the floor and subsequently framed the walls and had them laying flat on the floor system. We could still cover everything with tarps so the weather wasn't much of a worry but then there's the day when you stand up walls and then you have all that time and material exposed to the elements and then it's a push to get dried in. It was a lot for two old guys to do but after a bit of trial and tribulation there came the day when it rained no more in the building. I can't even begin to express the relief.

But I digress. I then began pursuing some woodworking projects that had long languished on my list of things I wanted to make. Most of those things were joined with dovetails in one manner or other. I had a very adequate array of chisels for this work but soon discovered that I did not have what I would consider an optimum set of chisels for these task. I found myself picking up and putting down tools really more than should be required and finally came to the realization that with a proper set of chisels I could eliminate a lot of unnecessary movements. I began putting together a list of criteria that would describe this set of chisels.





 I owned some shorter dovetail chisels that I really enjoyed, however they were 1/4" thick and given the way I typically layout my dovetails they would not fit between the ends of the tails to provide for incising the point where the side of the dovetail meets the baseline. In every case I had to put down one chisel to pick up another that was thin enough to fit.

Chopping base lines. When chopping to the baseline there should only be a minimal amount of material to be removed so an extravagant thickness is not required of a tool to accomplish this task. That sets one criteria. The second was length. It's nice to have a chisel short enough so that the base line where you're sticking the edge of the chisel and the top where you strike the chisel is in one line of sight. With longer chisels I would put the tip of the chisel in the base line and but when I changed my focus to where I would strike the handle the tip would move slightly. If you don't notice this then you end up with a wonky baseline. That sets another criteria to design for.

Personally I prefer good ole high carbon steel for my woodworking tools. At the last Forp Event where French/White oak was being worked profusely for days on end I noticed that everyone's chisels had serrated edges as the result of chopping in wood that had varying degrees of density. It didn't seem to matter if the chisels were A2 or PMV11 or High carbon steel. The end result was the same. The difference was in the time it takes to recover the edge. I realized years ago that a high speed steel edge that fractured took longer to recover than anytime one could possibly gain in edge longevity. I much prefer the sharper edge to be gained from using high carbon steel. I don't mind maintaining the edge as I work and when the edge does need to be restored with good technique it just doesn't take very long to be sharp and working again.

Evidently there are many others looking for a similar set of chisels because when I began posting pictures of the chisels I was making on my Instagram account I immediately started getting requests for these chisels. I took measures to get set up to produce these tools with a bit more efficiency and after a lot of trial and error and subsequent testing I was confident that I had a process by which to make very nice versions of these chisels.

The first 4 sets went out the door as soon as they were made and the set with Desert Ironwood handles pictured in this posting are the first I'll be offering for sale here on the blog.

As I mentioned this particular set has Desert Ironwood handles that all came from the same piece of timber. The ferrules are of course brass and the tool steel for the blades is New Old Stock Starret 0-1 tool steel. The overall length is 6". The sizes in this set are 3/16", 1/4", 5/16", 3/8" and 1/2". They are ground to have zero land on the edges but that edge is then broken so that it doesn't cut one's fingers as they are used. It's as minimal a land as can be had and not be dangerous to the user. The backs are polished and they come honed and working sharp.

The blade tips are taken into the heat treating process in a blunt state so that portion doesn't take such a beating in the hardening process and are subsequently ground back twice prior to final honing to make sure they are worked back into good steel.



The pricing on chisels prior to this set was $80 each and a five dollar per chisel discount for purchase of an entire set. I've had to source this Desert Ironwood and it's quite pricey material, for that reason these are priced at $90 each or $425 for the set.

If you're interested in purchasing this set contact me via email by using the contact button at the top of the page. (This set sold rather quickly, I'll be posting new sets as they come available so check back if interested)
