Fantastic square.
Fantastic speed square. Has all the marked measurements needed and the built in level is handy to have. This square is built right and heavy duty. Highly recommended if you’re a carpenter looking for a new one.

Well made
Well made, easy to read. I’m not using the bubble level near as much as I thought I would, but still handy for simple checks.

The t I t s
It’s everything a speed square can be. It will not fit into the holstery speed square holster because the foot is too thicc because of the bubble. The bubble is replaceable but good luck finding one. There are a few Johnson brand ones here in the way way back of Amazon, if you can make it down the rabbit hole, but the sizes are inconveniently advertised as fractions that don’t quite translate to 16ths of an inch. You would have to remove the bubble and then use a caliper, which I don’t have. I’m worried about it being stolen at work because there’s nowhere on the damn thing I can paint pen my name on it. It’s almost too many functions and I’m probably never going to use them all.

Awesome
I’m actually really impressed i haveMore expensive squares, including a trig jig I just hung on the shelf after getting this.This thing has a lot more markings on it and options than the others, and the level seems to be more accurate.. I’m 55 done construction the last 40 years

Clearly one of the best small squares out there
Super handy size of this square makes it a must have around the wood shop. Love the white on black easy-read markings. The price is right and it seems to be a quality tool. Was going to pay the price for one of those fancy smaller squares, but glad I didn’t. For what I would have paid, I could have three of these. Will definitely get another one to have as a spare.

Sehr guter Begleiter beim Handwerken! Habe Ihn gekauft, da ich nicht mehr mit diesen “weichen Stahl/Blechlinealen” der Schreinerwinkel arbeiten wollte. Ein sehr vielseitiges und stabiles Werkzeug in einer einfachen Form. Diese Größe passt gut in meinen Werkzeuggürtel.Der Kauf war für mich ein voller Erfolg!P.S. Wenn der Hersteller noch eine Libelle einarbeiten könnte/würde ohne die Form zu verändern wäre das ein Traum…

White writing on black stands out well. Better than my old silver natural aluminium colour. Metric is a bonus now.

Very good. I am just afraid the markings fade after a while being used.
