Had occasion to use my Quangsheng low-angle plane the other day. Blew the dust off the plane drawer handle, then blew the dust off the Quangsheng. Then realised the blade was pretty blunt.
So I blew the dust off the handle of the drawer of where I keep the Veritas honing guide and blew the dust off that. Then I went indoors to the computer to download the manual.
I prefer on/off buttons as you may have gathered although I must confess to a certain amount of satisfaction hearing that lovely planing sound as a wafer thin shaving came off.
