My 411 has not arrived and my 311 is very new, so no pants yet.

I can show 511 and 711 in Kydex or show how they do / don't fit the Spec Ops Combat Masters.

Can also do side by sides of 311, 511, 711 etc. if you feel any of that is helpful. Can also do photos next to other knives for size comparison.

For example, if you have a common folder and would like to see how it compares to one of the knives you are looking to buy....maybe I have something similar to place next to a SYKCO.
