I have a Benchmade knife that I want to carry further inside the pocket.
BM don't sell them as individual afaik.
Hiennie don't stock them.
the web has Spyderco deep carry clips but not BM.
Anyone know where I can get one from?
Do you have a picture of the sort of pocket clip you are looking for?
Knifekits in the US has a good selection, but like everywhere in the US, the options available for shipping very small parts to the UK is limited and are absurdly expensive. $28.80 to ship a $3 pocket clip! I bet that it would work out cheaper to ship to a person in the US and have if forwarded, or to have it picked up by someone travelling there.
It might also be possible to make one by hand by bending a suitable thickness of titanium strip. Probably more time and effort involved than it is worth though.
