I found too that the long-blade support pin is too small for all but very thin blades – like filet knives.
Since I received my RAM mount with the clamp attachment, I keep the tip near the vise and instead clamp the handle end to steady it. Many thanks to the guy who thought that one up.
From http://www.rammount.com/components I have four parts. The two arm lengths allow me to work a range of knife lengths.
Diamond ball base RAM-B-238U
Short double-socket arm RAM-B-201U-A
Long double socket arm RAM-B-2901U-C
Tough Claw RAP-B-400U
