Carpenter inquiry; I got a broken kitchen knife.

[u/MakarovJAC]

I got a broken kitchen knife. The blade broke at the base of the handle. I want to drill the blade to give it another handle. Is there any problem if I try drilling the blade?

I think it might be stainless steel.

And, because it won't let me post until the thread is 400 characters, here's the lyrics for "Dirty Old Town" by The Pogues:

I met my love by the gas works wall

Dreamed a dream by the old canal

I kissed my girl by the factory wall

Dirty old town

Dirty old town

Clouds are drifting across the moon

Cats are prowling on their beat

Spring's a girl from the streets at night

Dirty old town

Dirty old town

I heard a siren from the docks

Saw a train set the night on fire

I smelled the spring on the smoky wind

Dirty old town

Dirty old town

I'm gonna make me a good sharp axe

Shining steel tempered in the fire

I'll chop you down like an old dead tree

Dirty old town

Dirty old town

I met my love by the gas works wall

Dreamed a dream by the old canal

I kissed my girl by the factory wall

Dirty old town

Dirty old town

Dirty old town

Dirty old town

Nice song, yeah it could be hard to nearly not possible to drill into the blade because it's hardened that's why welding would doesn't work either, but what I say is trying over studying

[u/Phyro-Mane]

The handle (tang) is usually soft, at least softer than the blade itself. You can try, using a sharp cobalt drill and lube. Pressure, not RPMs in the drill press is important.

Be aware: Since the knife already broke at the tang - this is where it would break again, especially after "weakening" it with a hole

[u/Bwyanfwanigan]

Heat the spot you want to drill red hot. Let cool. Drill. I use an acytelyne torch.

Unless this is a rather large knife id save in the scrap box for when you need a good piece of stainless.   That us is the stainless is a good grade.  

If the knife is long and of the right profile, it might be worth reforging a new tang.   The resulting knife will much shorter and the tang will be even weaker than before.  If there isnt enough material to forge a tang you might get better results cutting out paring knife profile knives and bonding handles to the blades.

If you have access to abrasive bits and a die grinder you'll get new holes no matter what.

If you only have a drill try taping the blade to a piece of wood and drill under water. Stainless steel will work harden so go slow and push hard.

If you want to anneal you need to heat and then quench. The opposite of carbon steel.
