I recently picked up an old wooden plow plane. It came with 6 blades, but I first need to use the 1/4” for drawer bottoms. Trying to fit into my basic honing guide was challenging. Since the sides are slightly angled its really difficult to get to stay, and since there isn’t as much a bevel as chisels, it won’t go into the “rut” on the guide. Also, the location the guide needs to go for 30 degrees is right where the 1/4 section starts tapering into the wider section. Is there a method for sharpening these with a guide that I am overlooking, or is it a sharpen by hand kind of tool? Also, do the sides need to be “honed” to get a crisper side wall cut?

I just hone mine by hand. Make sure the edge is straight across and square to the sides. Shouldn’t need to “hone” the sides as long as they’re flat and parallel.

Goofy situations like this, along with the speed and convenience, is exactly why I ditched honing guides and learned to sharped freehand. It sucks at first, but it really don’t take that long to get the hang of it.

Alright. I messed around with sharpening by hand and managed to get it pretty sharp. I don’t have a good protractor to check it with. It seeems to cut well, but the sides are kond of scruffy, but I only tried on pine. I’ll try it on something harder later this week.
