I continue to be fascinated with shop made tools. This OWT (old woman’s tooth) was inspired by the work of Derek Cohen from Perth Australia. I’m getting interested in making boxes and embellishing them, inlays are in the future.

This is really the second one, the first one fell to the mistake of which side was the top. This second attempt was a lot quicker than the first, only taking about and hour.

It’s funny, I can’t find a source of individual allen wrenches to make the cutter, in these parts they are sold as sets with handles attached.

I need to refine the cutter and make a couple of more in different sizes.

Thanks again Derek, keep on blogging, it makes for a good read!

Looks nifty but what is it used for? I have never seen something like this before. Pray tell!

Nice OWT, too bad about the low availability of usable Allen Wrenches for the blades. You did a great job on adapting Derek’s design.

nice work on this hand tool… I am guessing it is just a tool to add torque while using hex keys…

What is an OWT used for? I have never see one before.
What size allen wrench do you need? I have lots of them from my days in the toolroom.
Can a piece of toos steel work as well. It seems to be a cutter for something?????

Try McMaster Carr. They sell them individually or by the set.

Really cool, it’s this shape we used to use in Denmark. (I have two, can send you pictures if you are intersted).

Here's a link showing some different ones, and how they're used. I admit I had to look this up.

Really nice looking router-plane. The more you use it, the more uses you will find for it.

All it takes is an Allen wrench for the cutter? I’d love to make on for myself.
