My Leatherman Surge Rides with me every work day. While I use many of its tools the blade exchanger has been neglected. I am always using screwdrivers, pliers, crimpers and the knife. So I bought a $5 scalpel off of ebay. I took it to the grinder and ground out a t shank shape and shockingly it fits in very nice and snug to the blade adaptor. There is a fair amount of grinding required but it is definitely worth it. Now I have an exchangeable blade I use almost every work day.
