Pshhhh...that's so lame, I mean it measures in degrees....real men measure angles in radians. I like to hone most my edges to an angle of pi/6 radians.
Woodworking is terrific for keeping in shape, but it's also a deadly serious killing system...
My work is precise, so I bought a protractor that measures in minutes and seconds. I use a pocket microscope to read it. Still cost less that $45

Ummmmmmm not to be an even bigger geek than I've already been in this thread, but errrr that's 12.5 degrees Steve. I think you mean 5pi/36?

Well I should confess, I didn't remember a lot of this stuff until recently, but I randomly decided to register for some undergraduate math courses this coming year (I work in higher ed so its free for me), so I've been reviewing a lot of basic trig and such as of late in preparation.

CG,
You are a far better man than I. Personally I would rather have needles in my eye.
Besides everyone knows you certainly don't need math for woodworking!!! …ummm...... wait a minute, ....maybe this explains why the drawer openings in my projects that are supposed to be "progressively decreasing in size in a proportional way" from the bottom to the top of the case never end up even close.
Maybe I should reconsider; what are those courses you're taking again? Shouldn't there be an app for this? Please say yes !!
Cheers, Mike
Okay, I admit- I think it's a cool tool, if not a bit of a luxury item. Most of my tools I know what I have them ground at, but I sharpen a lot for other folks and it would be a nice quick way to check a bevel angle, especially on power planer blades that I have found come in varying angles. I recently started sharpening those for folks with the Tormek. (Works great, by the way, with their planer blade jig).
I have that Japanese protractor thing... Somewhere... Deep in a drawer. I don't really like it, although mine does not have as good of a scale as the one Sean linked to. That one seems a bit easier to read than mine.
As as for aluminum tools, the Woodpecker tools are thick and well-made. A flimsier aluminum tool maybe not, but a quality one works equally well and doesn't rust. Question to ponder- does aluminum move more or less than steel with temperature changes? I don't know the answer to that. I would suspect more, so perhaps if doing machine work down to the microns an aluminum tool may have disadvantages, but for guys like me scoring a line and then cutting as close as possible to it, aluminum works fine.
... But for $50 I am probably out. I would rather buy a chisel or other tool for that.
Interesting. I really wasn't sure if you considered that steep of if you had converted wrong. I like my bench chisels (which are 01) right at 30 degrees and sometimes will even raise my narrow ones up a degree or 2 from there. I used to keep them lower than that but I found that they didn't hold up as well as I would like to chopping when below 30

All these cheaper solutions for the problem Woodpeckers has solved...but, guys, none of them are anodized in bright red! That adds huge precision to your work.
