I know it's dumb Mike because I've been seeing this acronym in all sorts of forums for perhaps several years, but I've never been able to work out what OBM stands for. Anyone care to enlighten me?
As to all this debate about how to sharpen I'll refer everyone back to a comment I made back in page three (I think) in this thread--- sharp is sharp. It doesn't matter how you get there, just so long as it's quick.
Well that's just my opinion. I learnt how to do this sharpening thing freehand a long time a go. I don't get too excited about the exact angles. If you looked at my tools it's obvious that some have somewhat convex bevels. Others have a concave one, and a selection are flat, and another few have two or three bevel angles on them.
As far as I'm concerned all those different forms of primary bevels are acceptable. They would be. I use the tools like that. What matters is the pointy bit at the end, and how flat the back side of the blade is.
Personally I have a great dislike for all the guides out there that I've ever come across and used, and I've tried a lot of them. They are restrictive forcing me to do what the guide wants to do. Not only that many of them I find aren't very good anyway, or at least that's how they seem to me.
The reason I've come across so many of these guides is because each year I teach fresh hordes of students how to tune their tools and sharpen the blades or irons. I show them the freehand style I use and get them to have a go. Many struggle to get it right, and I'm not going to spend a whole afternoon standing over a single student as they 'learn from the master' so to speak. That's how I was taught which led to the slightly embroidered tale
A lesson in Sharpening I posted earlier.
I suggest to students they consider buying or acquiring a honing guide to help them if they can't get the hang of sharpening freehand. There's no point in being completely put off their chosen career because they can't get the knack of sharpening freehand.
Of course, once they get the jig many can't get good results because they can't work out how to use them properly. That's where I come in and have to work out what they're doing wrong and correct their errors. And that's where I've developed a dislike of honing guides too. Too restrictive and you're stuck on the jig's narrowly defined path which isn't for me. I like to change things when I think there's a benefit and jigs and guides won't let me do that easily.
In the end I still go back to that old mantra. Sharp is sharp. Just be quick about it if working wood is a means of making a living. Slainte.
