I think the UKPK would be a great platform to do the custom shop. Maybe offer SPY27 and one or two other steels, a premium and a tool steel. Have a handful of different color G10’s/FRN’s, and maybe CF or Ti, to choose from. Maybe even have some different blade shapes like Leaf, Drop Point and Rescue that can be done in PE, SE and CE.
I say the UKPK because it is made in Golden and wouldn’t interfere any dealer exclusives except HH, which isn’t even in the US.
