Wax on, Wax off
There are so many sharpening systems out there, it can be rather daunting. Powered or unpowered, hollow grind or flat, single bevel or secondary micro-bevel, oil, water or dry, friable or fixed surface, open or closed grit, wax on or wax off.
I’ve come across another system recently, which has an interesting take on the process. It is the Precision Sharpening System from M Power.
It is based on diamond stones, and has two fixed angles 25° as a primary angle, and 30° as a secondary angle (such as for a microbevel). The stones are exceptionally easy to change, held in place magnetically. There are grits from 100 through to 1000 available (with the unit coming with a 220 grit and a 450 grit stone).
Where the system is somewhat different, is the direction of sharpening. Most systems have the grinding direction in line with the chisel, where the PSS works perpendicular to the blade. Secondly, most systems have the stone (grinding surface) stationary, and the blade is bought into contact and moved against the abrasive. The PSS has the tool stationary, and instead the stone is bought to the tool, back and forth, creating a flat grind.
It is an interesting grinding direction. Takes a little getting used to, but I can’t see that there is any particular disadvantage to the resulting tool edge.
The carriage is captive in the base, but has a bit of movement, which allows the sharpening surface to float fully on the tool. You can then apply as little or as much pressure as you like or need.
The body of the sharpener is best secured down, and there is a hole and screw made available for just that.
The system has a particular distinct advantage – speed of setup. There is no jig that needs to be set up, or clamped to the blade. The tool is placed on the flat bed, held against the lip at the side to keep it perpendicular to the sharpening stone, and a few swipes and you are done.
Remove the stone carriage, flick it around and a few swipes for a micro-bevel. Change stones in seconds to move between grades. It will not take every type of blade, but anything straight, such as a chisel or plane blade up to 2.5″ wide is no problem (3mm to 64mm). The ease of setup and repeatability means regular, quick touchups are no problem, and you may find you use it more regularly given the ease of use. With the result being continually, satisfyingly, sharp blades.
