Made to the same high standard as their try squares, this Joseph Marples mitre square model 19M has a spring steel blade securely fixed to the stock with steel rivets together with brass diamond washers. The hardwood stock has two brass faces fitted to the end for protection. The tool has a 230mm(9") blade for the accurate marking of mitre joints at 45° or 135°.

AccurateI have owned this for a few years now and despite the other reviews I've found mine to be perfectly accurate and extremely well made. With light use in box making I expect it will last me a lifetime.

Not 45 DegreesThe acute angle on my Joseph Marples mitre square is not a true 45 degrees. I checked it using a Japanese mitre square and a 45/90 triangle. Both give the same result. So much for Marples products!

Mitre been betterI am sad to say that the stock of the mitre I purchased was not parallel. The result was that the acute angle was a perfect 45 degrees whereas the obtuse angle was about 2 degrees out. If you purchase this item, check it before using it. Better still, use an all metal variety.
