I've got a lot of tools, but nothing matches the RONGPRO Multifunctional Rafter Square. Yeah, it's a 7-inch triangle carpenter square made with die-cast aluminum alloy and an orange finish - but what sets this thing apart is its versatility. You get a mini steel ruler that you can extend out at different angles, or pop off entirely so you can set up complex measurements fast. And I love the stainless steel ruler too - it's laser etched for max readability and accuracy. Plus the level vial gives me greater control when crosscutting lumber!
If I had to name one downside, it'd have to be price tag (it ain't cheap). But honestly that makes sense considering how solid and durable the build quality feels on this baby - no corrosion here! Even better than my old rafter square by miles.
All in all, must say I'm extremely pleased with my purchase; shoutout to RONGPRO for making such an awesome tool – totally worth every penny!
