If rough edges or burn marks mar your scrollsaw work, particularly thick stock, here's a possible solution. With a blade in place and your scrollsaw running, gently touch a metal file to both back corners of the blade. The rounded back corners enable your blade to cut tighter curves without the corners digging into the wood.
