There is a simple way to adjust the saw for different blade thicknesses,
which will solve that problem. Check the Knew Concepts website for that
and you will stop nipping off the ends of blades.
I had an old "German" saw frame that was o.k., bought another one with a
larger throat size, it still said "German" on it, looked exactly the
same. It was a piece of rubbish with so much extra space in the various
spots to tighten things that I wonder if it was a non-German
counterfeit, or if that garbage is what they are passing off these days.
I use my Knew Concepts saw frame for all work now, down to 10/0 blades,
which do not break in that frame unless I get careless. Best saw frame I
know of for gently tightening 8/0 and 10/0 blades. My daughter uses a
"German" saw frame, borrowed my Knew Concepts, and was amazed by it.
She is getting one for Christmas. (Don't tell.)
While my daughter was borrowing my frame I had to use hers, and if you
are old enough you will know the difference between power steering and
non-power steering. Knew Concepts is like a feather, heavy "German" saw
frames are like a truck without power steering. My two cents.
