Don't give up on the cheep-O alum square. You can have a number of them and when the get stepped on and bent no big loss. If I paid $100 for a square I would be afraid to use it. The are always dropping on the floor or getting pinched some place the should not be. You can cut them up for patterns and straight edges with out worry. I look for the silly squares all in 1/8th. I can't remember the last time I used 1/16th on the framing square anyway. The light alum. square stick to the pitch oozing out of fresh cut pine so you marks doesn't wander, as a perk, the benefit to working with pine and a lighter square. But as time goes by I think I should saw more of the sap wood off my pine timbers.
I do have a shinwa, too.
