Cutting ply. Moved offcut with left hand. Thumb was too close to blade and bam , tip of thumb went into blade and blade was gone as soon as I felt the knick. Loud bang like a balloon pop. Bandaid instead of ER trip. Never wanted to test the saw but glad I had it tonight. I take full responsbility for my error. These gingerbread wooden houses will have a very special memory for me.
