I WAS hesitant to buy this measuring tool but I`m glad I did. Thanks to my knowledge gained in practice, I can confidently say that this is a must-have for all industrial and scientific woodworking projects .The detachable feature makes it easy to handle while still being durable enough to withstand wear and tear. The aluminum build gives it a lightweight feel making it easy to carry around. The only con I've come across is that the increments could be better marked for more accurate measurements. Overall, a great purchase for any woodworking project!
