Highlights

Metallic CBN Sharpening Stones from Poltava Diamond Tools are designed for guided knife sharpeners (Hapstone, TSPROF, and other Edge Pro-compatible systems). CBN (Cubic Boron Nitride) is the second-hardest material after diamond, providing high endurance and low wearing rate with copper-tin alloy bonding.

Description

The Premium series of Metallic CBN Stones features a 3 mm thick CBN-bearing metal plate mounted on a high-quality aluminum blank. The CBN grain is made in the USA.

CBN offers exceptional hardness, strength, abrasion resistance, thermal, and chemical resistance, surpassing synthetic diamonds and conventional abrasives like silicon carbide and aluminum oxide.

Due to its high thermal stability and chemical resistance, CBN is suitable for sharpening in conditions where synthetic diamonds are not typically used. CBN stones can be used without lubricants, making them the cleanest option among available sharpening stones.

Not OEM material, doesn’t slide as easily. Feels like it will last longer.
Color: Grey, Color: Grey
Thought it was going to be the same quality as OEM, might last longer but definitely has a different texture. Fits well.

Very happy
Color: Grey, Color: Grey
This is a 3d printed part. It fits great, looks excellent, works fantastic. I bought the grey version. Work the part in carefully, take your time. The seller’s video in the description is very helpful! Great alternative to dropping $100 on a replacement. Excellent value, fast response and shipping..

Works for E46 M3
Color: Black
Great customer support, fits like it should, is a nice detail that you’ll notice if yours is broken. Looks like OE. This is my first 3D printed part, I hope it’ll last another 20 years. Has lasted almost a year so far!

Flimsy, pretty obviously 3D printed. It's noticeably blue in color, but no one in the front seats will notice. This is good as an aesthetic bandage fix, but I'll go back to sourcing an OEM piece.

Poor quality.
Color: Grey
This is a waste of money. No communication from seller. It took super long to receive it and when I got it , it was a big disappointment. This is a junk.
