This selection of Rosewood tools represents the very best quality Joseph Marples produce. They are based on designs of the tools last made over 70 years ago, which carried our ‘TRIAL 1’ brand, or Corporate Mark.

The squares have 1/8th inch thick machined brass on both the inside and outside faces, thus ensuring accuracy on the inside and outside edges. They have a blued spring steel blade, secured to the stock with brass diamond washers and steel rivets. The accuracy of the try squares is well within that required by BS3322.

The Screwslide mortise and Marking gauge has a full 1/8th inch thick brass face. The stock is locked on to the stem by brass knurled thumbscrew and protective pressure pad. The locking screw is set within a traditional brass protective shield. A screw slide gives fine and precise adjustment of the mortise pins and on the back of the stem is a single marking gauge pin.

Trial 1 squares are tested on both internal and external faces and are both
accurate to better than 0.001”/” nominal size.

A fine sealed rosewood Trial One sliding bevel with a 9" (230mm) blade. This sliding bevel combines rosewood and brass to create a lovely user tool. The bevel is secured by a brass knurled locking adjuster that allows the blade to be secured at any angle. Made from the finest rosewood with solid brass edges for extra protection against wear and tear, this bevel is made to last. The pinnacle of a Sheffield made product.
