Not much more to be said. I will add that as an older feller some days my hands are not as steady as needed to hold the slight angles needed for the 2nd and 3rd bevels, those that really make the difference between sort of sharp and really sharp. You know, the sharpness that makes a tool a joy to use. The sound of a hand plane when this sharp is nearly addictive. And, being able to plane to finish, where the wood can’t be any better for when you add the finish (of your choice) is very satisfying and rewarding. It is so cool to be able to do this, but you need these last two bevels to do this, thus the angle guide is a must while developing the muscle memory (or if you’re an old poot like I am and need the help now and then) or skill to sharpen to this level of proficiency. As written, a well thought out and helpful training device. Well done RC. And I’d be remiss if not saying that the transaction was seamless and the customer service exemplary. Great experience all around.

The review title says it all. I’ll only add that this not meant as a permanent tool. I bought the guide to help develop adequate “muscle memory” (At nearly 70 I am not as steady handed as I used to be.). And as ALWAYS the Cosman customer service is exemplary.

everything I’ve get from Rob Cosman is top-notch. I was curious if this would make my life easier and boy has it ever!
It’s way more consistent than my own hand, pressure and guessing angles.

Very precise &great materials. Will be a very durable tool.

Great training tool! You have to be careful with the very powerful magnets of this training tool as it can snatch your planing blade right out of your hand, just be prepared. They are very strong magnets.
