Hollow ground blades

Mick and Duane are flat grinding the blades now. But I heard if you want hollows, you can order hollows.
 
Thanks! I prefer a hollow grind and like the edge on my S-2001.

Does anyone know if the flat grind is an improvement or does it save cost in the production process?
 
Heck, I'll try my hand at this one too! I do recommend reading the FAQ section here on the forums. joe Talmadge answered your question in much greater detail than I shall attempt here.

Hollow grinds allow a thin edge that is easy to sharpen for a while. Generally speaking, they are great for shallow cuts (where the depth of the material is lower than where the hollow starts to widen. if you are cutting thicker materials, they can have a tendency to bind in the hollows. A flat grind has a great shearing effect for thick materials. E.G., cut a thick piece of meat with a shallow hollow ground blade and with a flat grind, adn you should feel like the cut is easier. Also, generally speaking, the flat grind makes for a tougher blade than the hollow ground blade.

Mick and Duane ought to be able to give you more info. Again, this is all quite general. people have been using hollow ground Striders for quite a while, and from what I ehar, they perform well! Also, look at Jerry Hossom's hollow ground blades. They cut liek they're not supposed to! And they're supposed to break! I swear!!!! But they don't. :)


Personal preference? FLAT GRINDS RULE! Of course, flat grindign is all I can do onmy little belt sander... :)
 
We now use a full bevel grind. Which is a flat grind that goes all the way to the spine.
I believe it out performs hollow in every way.

Actually, it costs significantly more to grind the way we do now.


More on this soon

I realize that this is a very un-scientific test but I did a comparison with my hollow grind BT and new style flat ground BT. I attacked an old cardboard box in my garage (it made the first move..I swear) and found that there is quite a bit of difference in the way the two blades cut. The hollow ground blade would make shallow cuts with a minimum of effort but deeper cuts required quite a bit more force and the blade tended to bind. The flat ground blade on the other hand zipped right through the cardboard.
When I first found out they were changing their grinds I asked if I could order my BT (serrated spine, tiger stripes) with the old style grind because I thought it looked better cosmetically. I was told that wasn't an option and assured that they changed the blade grind to make them perform better....they were right. I was sceptical at first but I've seen it first hand, the flat ground blades cut much better than the old style.
 
Haven't tried chopping wood with my BT yet...that's what I use my MSC 7.5 for. Hmm..I could trim a little more off the tree in front of my house just for fun.
 
So is there any advantage to a hollow grind? Maybe slashing or something? What about a quick in and out stab?
 
If you're stabbing your knife into something (a person, for example) the grind of the knife isn't going to play a big part in how well the tip penetrates. Blade shape is a lot more important than the grind when determining how well a knife penetrates.
 
So the bottom line is, there is really no reason to choose a hollow grind over a flat grind except for cosmetic appeal.
 
I think flat grind is easier to produce therfore they can make more to boost profits. It is also a stronger blade type IMO
