Review: Very happy with my purchase, but....... - I've seen a few reviews complaining about the sharpness of this plane and so I thought I'd offer my opinion on it. It's a nice little plane, fully functional, acceptable quality, and .................blunt. So what. Every bladed tool you will buy will need sharpening before use. It took me all of 90 seconds to sharpen, and another couple of minutes setting the plane. Now I have a very nice piece of kit that didn't cost the world. But a word of advice. If you're going to buy one, you have to invest in some diamond plates and a leather strop. You not only need these for initial set up, but also to keep the iron sharp going forward. Hope this helps.
Review: Doesn't work straight out of the box. - Well made tool but needs sharpening and setting ip before use. Blade was completely retracted on opening and completely blunt. Wouldn't cut at all. Videos on YouTube show you how to put an edge on the blade using an oil or wetstone.
