Review on Nitram Sharpening Bloc: Continual Sharpness with Easy Refills by Jason Wolf

I recently tried out this sharpening bloc and refill set and was pleasantly surprised by how quick and easy it was to sharpen my tools. As my tests showed, the sharpening bloc was highly abrasive and effective at removing dull edges. The refill pack ensures that the sharpening power is consistent throughout multiple uses. The only con I noticed was that the bloc could be a bit larger for larger tools, but overall a great product for industrial and scientific applications.
