If the tang angle on your scythe blade is too high, it can be compensated for by adding a wooden wedge, in between the snath and the tang of the scythe blade. This has the equivalent effect of reducing the tang angle of the blade.
It can also be very useful for fine-tuning the lay of the blade, when you are using a hook-nosed scythe blade, like the 2010 model that I sell. If you are having trouble with the hook-nosed tip catching and digging into the dirt, adding a small wooden wedge like this, can correct the lay of the blade so that it glides smoothly over the ground. I include one of these wooden wedges with every 2010 blade that people order from me, but you can easily make your own, and even make a variety of sizes, for a very fine-tuned, customized lay of the blade.
