No Turbo actually I don't do a lot of abo knapping although I have been leaning in that direction more. I have been working with antler punches and hammerstones but I learned to Knapp with copper so I rely heavily on my copper tools. Kind of like a crutch. I took the name Abo mostly because the nick name I go by is Ab so it just worked for me. Thanks for your reply. What tools do you use?
