JT-21
Okay, I know I said I don't usually do product endorsements but like this one is really pretty alright too and I think people should know. So here it is:
The Arrow JT-21 staple gun is way better than the T-50.
Why? Because unless you ran out of nails or you're trying to tack things into cement or something, you'll never need a T-50. It's tempting to think you'd better go with the stronger one when it's hanging on the shelf at the hardware store, but don't be fooled! The T-50 is inaccurate, the bigger staples are harder to pull out when you screw up, and it's just a paint in the ass to use in general. During my freshman year in art school, my entire Painting 1 class sat around and stretched canvas together. And all the kids with T-50's were struggling the whole time cursing they're staple guns.
Long live the JT-21!
