Hello.
I bought a Damascus knife blank last year and finally started work on it this evening. It's a full tang knife I got from a stall at the Ludlow Castle christmas market. The blade is ground but not sharpend. I decided on pins and wood, so started drilling the tang. Having tried bits from three different sets and sharpened bits a couple of times I've still failed to make much of an impression. One of the drills is a Cobalt coated HSS item. I would assume that the blade has been heat treated already, but a decent file and an 'old hacksaw blade' scribe have both scratched the blade, as a test.
So whats going on?
Are all of my drill bits duff?
Is the blade hardened?
What drill bits should I use if it is?
Any help and answers would be good. Thanks.
