I just acquired a 15000S knife which I plan to use while fishing. I love the knife but wish it had a lanyard hole. Anyone have advice on how to drill one through the D2 steel? Thanks!

  Carbide bit with the blade locked snug in a good vice on a drill press with the slowest speed possible and maybe some continuous lube action would be my unprofessional guess.

  Quoting knife maker and heavy consumer of D2 steel Tom Krein off another forum,
  
  Carbide is the best way to drill holes in hardened A-2, or D-2, or any of the air hardening steels. It is pretty tough to spot anneal them! As has been stated no coolant is the best way to go. You can use coolant, but it must be a constant stream. Don't get it hot and add coolant as you will shatter the bit/end mill. A drill press is a must with carbid. It is a brittle material and they shatter easily if miss used. There is a learning curve, but you can learn from our mistakes. This is good as a good bit is expensive!! Be careful breaking through, light feed is needed. One thing I have heard, but not tried is a masonary bit at high speed. Masonary bits are much cheaper and more readily available. It won't be a perfect hole, but you could drill it oversize and then peen a piece of brass in the hole and then drill your hole exactly where you want it. Tom

  Great, thank you! I'll try the carbide drill bit route. I could probably get by with a 1/8" hole since I only need to fit a single strand of 550 paracord through it.

  Yeah, it would have been nice if there are lanyard hole pre-drilled.

  Maybe I missed it somewhere else, but been wondering how this worked out for you.

  Speaking of the subject, if you need lanyard then you are drilling through liner and not the blade. I don't think BKC uses D2 for liners. IMMSC, it would be 420 or something line that?
