Wow that was just what I was interested finding out. You really hit the nail on the head. I have another question I think you could help me withif you would be so kind. I have an addiction when it comes to purchasing new knives. Lately I have had to scale back on what I can spend on Tactical folders and have been purchasing knives from Benchmade, Spyderco, Buck, and now Myerco. I have been buying their recent models made in China. They all seem to be excellent in their fit and finish and use very good materials. They all have very heavy solid Stainless Steel liners. I have gone for the less expensive models over the past year due to the economy and having my income drastically reduced and a new bug up my but over Great Eastern slip joints. I have a thing for times past like Fedoras, pocket watches, fountain pens, flint locks, traditional / primitive archery, and Cowboy action shooting and now a new fixation on more traditional knives like I would expect to find among my Uncles, Grandfathers or an old west cowboys things.
Back to the less expensive Tactical folders. I really like each and every one I have purchased. They all have one thing I really want to alter. I want to drill holes through the liners to lighten them. They would all be the cats - _ _ _ if I could do this. I have built many 1911 pistols for IPSC and several flint lock rifles and pistols but I can not get a store bought drill bit through one of these liners. They all just burn no matter the speed, pressure, or use of machining oil. What bits do I need and where can I get them? I have a Brownells catalog but need guidance in selection the necessary bits.
Im really thankful for the information you have already given to my initial post.
