I have always used Olsen blades until my last order.
I bought patterns and blades from scroller on-line and
bought the Flying Dutchman blades. These are definitely
much for aggressive than the Olsen blades were so,
you may want to try some Olsen blades or some from
a local wood crafting or hobby store.
Of course, the cheaper plywood will probably be more
prone to chipping than good Baltic Birch but, I have used
the cheaper wood and, once in a frame, the edges don't show
and that's where most of the chipping occurs.
Good luck and God Bless! Spirithorse
