Heat Treat Service
Well, there's a bit of a surprise here. Canadian Knifemaker Supply Ltd is no longer offering heat treat services. Heat treating is still being done by Rob Ridley - but is now separate from CKSL. Website is up and running call but you can still get in touch with Marilyn at 403-556-1113.

Unfortunately, this means that you won't be able to request supplies sent back with your heat treat.
