Also a very good option for inhabitants of the good ol' RS of A, a local product that does well in the mid-range market, also a very good blade for the price you pay. Let us support our local manufacturers, we will happily endorse this product.
These blades are by far the worst I have ever used. I believe they are designed to nick you so that you may appreciate higher quality blades.
I found these blades to do the job just fine. I dont have the toughest beard around but worked well for me. Well worth a try at the cost.
Obsidian is one of the sharpest materials around. You could get a good shave with it, at the risk of slicing off skin, digits or both. You can not with this blade. It’s alright to shave really long hair, ahead of a decent blade. Or to shear body hair. Wouldn’t trust it for much else. Used the blades as a letter opener. Worked for that too. I’d be curious as to whether, after a good strop, the blades would perform better. I’m unfortunately not curious enough to try it myself, as I’ve already been let down but this blade.
These are like shaving with a rock! Worst blades ever.
