I have a small 16 tpi crosscut-filed molded spine saw by Veritas. This is slow and tends to bind even in thin material. My Japanese saws cut much better. I'd like to refile it to dovetail configuration, i.e. rip teeth, to see if I can make it a user. I'll take out the bevel angles. Should I alter the rake to a more aggressive 5 degrees (currently 15)? Thanks.
