I would suggest that you not do it...
If you do, it will make other approaches to a repair close
to impossible particularly if you might want to glue it in
That said, are the cracks such that with proper clamping
they could be brought back together? (Don't worry about
methods of clamping it just yet.)
All the best,
I will mention something else...
I recently purchased a very fine cooking knife from Japan.
When it arrived, I soon saw that the handle had a small
chunk missing, and the missing piece was nowhere in the
Of course, I first thought that I would just contact the
seller, and get another that was undamaged, but then, I came
up with another solution:
I went to my shop, found a piece of hardwood of a color
similar to the handle of the knife, sanded it to generate a
small pile of dust, and then mixed that with some epoxy
until I had a paste texture.
I pushed that material into the space, allowed it to cure,
and sanded it off.
That was perhaps a month ago and I can no longer find the
All the best,
The cracks are as much as 1/4" in width- so an option is to fill them
but good luck matching the wood/grain structure I think. Maybe I'll
remove it (it is a working saw) & install a 'working' handle...thanks
I collect and restore old tools and have had some success repairing cracks in
handles by gluing and clamping. A 1/4" crack is pretty major and when you
clamp it, more cracks are likely to appear. The trick is to re-moisturize the
wood. But you can't just drown it in a bucket of water.
I've used various methods to steam the wood to increase moisture content,
rendering the fibers more pliable before clamping. One technique involved
boiling a large pot of water on the BBQ with the handle suspended just inside
the pot but above the waterline, using a grid I made with coat hangers. I
covered the pot with aluminum foil with a small opening to vent the steam.
The covering doesn't really elevate the pressure inside the pot but it
concentrates the steam from escaping too fast into the atmosphere. You'll
need to steam the handle for at least a few hours. A light coating of
vaseline on the handle can help to protect whatever original finish still
remains on the wood.
After you've cooked it for awhile, set it aside to dry so that excess
moisture at the surface of the exposed wood fibers (in the cracked area) can
evaporate. Use a good yellow glue (TiteBond) and clamp it up.
Smaller cracks can sometimes be drawn together with a web clamp or an old
rubber bicycle tube (or surgical tubing). A crack as big as 1/4" will likely
require the pressure of a screw clamp. Trace the handle onto a piece of scrap
wood (before you steam it) and cut out the profile in two pieces to use as
clamping cauls. The flat areas on the outside edges of the cauls create
parallel surfaces for the clamp jaws and the profile on the inside edges of
the cauls distribute the clamping pressure uniformly. The cauls also protect
the handle from damage by the clamp jaws.
It sounds like a bit of fussing, but it's rewarding if you can successfully
restore the old timer. And it's cheap, too.
If you check the pot and find it full of gravy... you boiled it too long!
Good luck. I hope you try it.

Well, if you just want a functional handle, I would consider filling the
void with epoxy. I find that it planes/scrapes/sands quite well and the
clear "color" blends in for the most part. Use a heat gun, gently, on the
wood and the epoxy to reduce the viscosity to get it to flow into the joint.
I recently made a knife handle for a buddy who had old kitchen knife that
was falling apart. I had to fill some small voids in the new handle. After
filling the voids, I coated the entire handle in epoxy as a "finish". After
a 2-day cure and a little wetsanding it was a pretty comfy handle.
My goal was create a nice-to-touch surface that would hopefully stand up to
the periodic dunking a knife gets in a normal kitchen environment.
I'm not suggesting that this the proper way to build/finish a knife handle.
I just tried it and it worked pretty well.
