No big deal, just a nice little afternoon project. This will help me with my dovetails, my store bought knife just doesn’t make it in far enough. Made with a surplus sawzall blade and some leftover wenge and brass.

Hi Willie,

What I did was buy a 5/32” brass rod at Ace, I keep it in stock around the shop. Glued the blade into the handle, just to keep it in place, then drilled through the wood and blade at the same time with a cobalt bit, you will need to maybe dip the metal into water if it starts to heat up too much to prevent the tool steel from losing its temper. At this point, the handle is oversize and coarse. Cut a couple of lengths off the brass rod, a little oversize, then drove them through the handle and blade with a hammer. Ground them down close to the wood with the bench grinder, and then used the large disk sander to make everything flush and get a good shape for the hand. After that, I refined the finish with a cat and mouse sander, and then by hand sanding. If you use the same drill size as the brass rod diameter, it will be a good interference fit, and will hold nicely.

Nice Jerry,looks great and more importantly, functional. I put one of these together with same materials( minus the exotic) and same techniques. Only I went with a shorter exposed blade length and now wish I had given it a little more reach like yours. Oh well, they are fun afternoon projects so perhaps a new one is in the near future(w/some exotic this time) LOL!.......ROB
