+ 1 on this. I have an assortment of Japanese style saws - nothing 'timber sized' - the ones I have are very useful for furniture, small scale timber work, and random carpentry work. And I have one that I use for field work - trimming pegs, etc.

But for cutting timber in the shop - I'm a big fan of a full size Stanley saw for tenon work. Cuts flesh as easily as wood. I think the one in my box now has the same blade pattern as the 'sharp tooth' - but is definitely not disposable.

Wooden handle, feels good in the hand, and you can play a tune on it.
