Resin bound whetstone 400 grit  

Fixed on plastic baseplate with non-skid rubber feet  
  


This sharpening stone uses resin to bind the abrasives, in this case white aluminium oxide.  

It does not soak up water and therefore does not require frequent wetting. Super Stones wear slowly and maintain a constant sharpening effect.  

  
  


Splash with water before and during sharpening, do not soak or store in water.  
  

- Measurements: 210 X 70 X 20 mm
  
  

**About grit sizes**  

Whetstones come in various grit sizes. The higher the number, the finer the grit. A finer grit results in a sharper knife. Sharpening a really dull knife on a fine grit will take much time, so you will need to treat it on a coarser grit first.  
  



* 120 - 600: Appropriate when real dull knives need to be brought back in the right shape

* 800 - 1,000: Appropriate to sharpen knives that were already in a reasonable state

* 2,000 - 3,000: For a result sharper than most knives are when they leave the factory

* 5,000 - 12,000: To polish the knife and get a razor sharp edge

deze steen gekocht om de wat botte messen voor te slijpen.
krijg nu de messen vlijmscherp. 


Een erg fijne slijpsteem voor het geld. Geeft genoeg feedback tijdens het slijpen en zorgt voor een mooie gelijkmatige snede. Vooral om de slijphoek te veranderen is hij ideaal. Wel oppassen met de wat hardere messen. Ook al is het een harde steen, je kunt hem nog steeds beschadigen. Al met al een aanrader voor het geld.
