chipper blades

I have been sharpening blades for a few years now & have seen many made from various grades of tool steel. It is not just the steel that makes a good knife but the hardening & tempering process. I have had customers complain that some pattern knives dull quicker than OE's. Saturn use Bodycote (specialists) for the treatment processes but some blade manufacturers do it 'in house'.

There is also the grinding/sharpening process which if not done correctly will over heat the blade and soften the steel. Another problem I have found with TW blades is an incorrect angle caused by the hollow ground Radius being off of the center of the cutting face. This can cause a drastically different angle at the cutting egde causing all of the associated problems including much faster dulling.

I grind all blades on a precision grinder using very accurate tooling/fixtures, not only do i get a much better finish but blade angles & the hollow ground radius is allways spot on. I have seen many blades ground on aftermarket blade grinders which have a very different angle to the manufacturers spec.... :ohmy

Hi,

 

We're currently redesigning the lazer etching on our blades and wondered if we could get your feedback.

 

Our blades are made out of Uddeholm Steel and wondered that actually meant anything to you?

 

Do you know their steel is the best in the World?

 

Should we just put "Made from the World's best steel" or nothing at all.

 

Thanks for you thoughts.

 

Cheers

I used to use Saturn knives when I had my TW150 - never had any problems.

I now use their discs on my greenmech and am quite happy with those.

 

If you are nervous of non OEM bits just shell out the extra, but I'd say there's lots of us who have been quite happy with Saturn.

 

As for the knives being the key component - ask any TW mechanic and I suspect there are some other bits that are more vital but thats another thread!
