Dewalt single edge pull saw vs Shark saw dual edge pull saw, with an oldie at the end.

I saw this saw while cruising at my local Home Depot. It’s alright but kinda wished I used my $20 on something else….
WARNING!!!
Do not test saw sharpness on your hand! I’m a untrained idiot who knows just how dull his saw is.
Do not do this stuff at home!!!!
