Probably a bit stiffer but otherwise, pretty much the same. Using the card scarper instead of sandpaper is faster, cleaner, much better at flattening the surface and also a lot more satisfying to use.
True, for ski base shaping the card file is really stiff. For removing fine hairs and smoothing and for wax removal the card files I use are fairly flexible.
DOGPADDLE CANOE AND WOODWORKS
Soon to become a paddle. All parts cut. 17 pieces plus Dynel edging (not shown). The shaft core-last piece in the rear- has already been laminated from 2 strips of red cedar. This will be a Shallow Water Special. Progress photos over the next several days.
