Yup, the only reason I said anything is because I met a guy at a shoot last summer who had knapped a lot inside. His wife would bust him because the TV screen static would pick up the dust and she'd know he had been knapping in the house again, he has some fairly serious lung issues now after 16 years of indoor knapping. He does abrade like a madman thought. You had some good ideas for the winter months. Maybe even hafting methods and arrow/spear/atlatl dart making with your stone points in the winter. Have fun, dpg
