Review on 🔪 Mobius + Ruppert (M+R) Sharpener Replacement Blades - Pack of 10 - Made in Germany - Unsurpassed Quality! by Morgan Gilmore

I work with colored pencils and we have to sharpen the pencils very, very often. I've used manual sharpeners and spare blades from another German company, but my last two or three packs of spare blades weren't sharp at all and gnawed at my pencils. I decided to try the M&R sharpener and blades which I have been using for about 4 1/2 months now. In that time I have used and replaced 10 blades. Since the new blades are very sharp and work very well, I put them away without hesitation. As for 4 stars instead of 5, in my first pack of 10 blades, 2 were not sharp at all. I put pencils in the sharpener and struggled to get a sharp point. I found that when I rotate the pencil, the sharp blade almost retracts into the sharpener. Despite a couple of dull blades in my first pack of 10, overall I'm happy with these blades. I hope for more stability in my next packs.
