there is a difference in cutting the same way and it being as easy.
obviously if you are cutting a 2" strip off a board it wont work.
but if you want to do anything bigger then i dont have a problem doing it.
just do a light cut first with a knife and straight edge then remove the straight edge, run the knife down the cut a bit harder and snap it.
i have said all along it isnt as easy as P/B i am just saying you can cut it with a knife.
