A good mortice chisel needs to be robust to withstand repeated heavy use when chopping out mortices or cutting other joints. The Rider mortice chisels fit the brief perfectly. They incorporate a couple of refinements to make them easier to use and achieve better results.
Starting at the top, a steel hoop prevents the handle splitting from constant mallet blows. A small button of timber protrudes above the hoop to minimise damaging the mallet head. The handle is dense European Hornbeam chosen for its resilience. Sanded smooth and given a light oil finish, the Hornbeam has a superb feel in the hand. The handle ends in a polished stainless steel ferrule with a shock absorbing leather washer between the handle and the chisel’s bolster.
The forged blade is Cr-Mn steel and is heat treated to 59 HRC. The steel’s fine grain ensures a keen, long lasting edge. The bevel only requires honing before use. Although, you may wish to sharpen with a steeper secondary bevel, depending on the type of timber you are using.
Improved cutting performance comes from a slight taper in the cross section of the blade, the top being slightly narrower. There is a fractional taper in the length of the blade, less than 0.5mm over the entire length. These tapers give just enough clearance even in a deep mortice to stop the chisel binding in the cut. The blades are approximately 140mm long with the overall length 305mm. European made.

rebranded Narex (probably)I have seen a lad with a set of these chisels at the college and by comparison they are remarkably similar, if not the same as the Chezh Narex chisels, they are very hard and keep a great edge. Notably the new edge of the chisel is very brittle, but they improve with sharpening as the outer brittle layer is taken off the end. If they are indeed Narex chisels, they are ground prior to the molten salt hardening process)

12mm Rider Mortice ChiselGreat value for a chisel but the quality of the blade is poor. Spent more time sharpening than using. This would be fine for soft woods but hardwoods, no. If you are planning on cutting a lot of mortices spend the extra on a quality tool like the Lie-Nielsen. Thats what I'll be doing.
