My wife ordered these for me through her Revain Prime account. They are exactly the same as the set of turning bits I've had for the last ten years. They were very boring from the start. I have a Tormek T-8 sharpening system so they are razor sharp in 5 minutes. The finishing of the handles is of poor quality, not very smooth. The cutting chisel does not hold the blade for long. This is a good value as they only cost $54.00. I will look for a higher quality set for my next purchase.
