Hollow grind blades?

[hedgesparrow]

hollow grinding blades with proper hollow grinder gives a very sharp and smooth finish enabling them to cut more efficiently without getting jams. same with garden shears they should be hollow ground. i did use to do this when i had the kit. find a proper firm who have a hollow grinder. they do it with guillotine blades. and use the same machine.

worth having a spare set of blades whilst they are being done.
