Support BladeForums! Paid memberships don't see ads! A little late checking out this sub forum! Natlek....LOVE that one! Warren, you know I have a fondness for your blades too! Brian, my main concern was an exposed heel, so the plunge had to go somewhere (could do no plunge, but that brings it's own challenges), and I basically just copied my 4" hunter model in that regard. Gave the spine a slight S curve instead of being straight or arced, as I couldn't make those look right to me. Because of that, it's not quite 2" from the heel to spine, just under it. 1 15/16" about.
