"Double Cut"?

[Strabs]

I think morimotom has the most right answer. My understanding is that double cut means bead blasted with two different mediums. I don't know what those mediums are. Maybe glass and sand?

Yes, two mediums.

First would be Aluminum oxide to tear up the surface.
Second is small glass beads...very thoroughly (aka-a real long time) to slam the surface smooth again.:thumbup:

I'm assuming then also that this new Tank Buster is more blade heavy than the SJ TAC? Wider blade?

Also, when Busse says "heavy swedge", does that simply mean that the false edge is left blunt?

Thank you.

the swedge is not sharpened. i think by "heavy swedge" they are referring to the length and acute grind, making it a fairly large swedge.

the blade is wider than the sj, so in all liklihood heavier. how much, we won't really know until someone has both.

i can never remember the process of the first cut. i just remember it is given a rough satin finish.

for some reason i was thinking it was sanded, but i stand corrected.

Morimoto, you are correct on the satin finish prior to the blast cabinets. I just forgot to acknowledge this step.
They have to put them onto a belt first in order to create a satin/smooth finished enough to remove stock imperfections, then they are hit with the two blast materials. This is why it costs nearly as much as a full satin treatment...lots of shop labor.

so are they actually triple cut??

or do the two blasts count as one cut?

Once upon a time, I found a quote from Jerry that describes it:

A "double cut" is exactly like it sounds. We have set up two large blasting cabinets. One has an abrasive media and the other has a very fine glass bead media. We hit the blades in both cabinets and the combination seems to close off the pores of the steel much better than just a single blast. This seems to offer better resistance to the elements.

Unfortunately, I can only find my quote and not his original post.

Oh man, now I'M confused

Does double cut offer better protection from the elements better than a coated blade??

No, the order from most protection to least is: Coated, satin, double cut, competition (the de-carb layer rusts quickly). INFI is not stainless but is highly rust resistant. To be sure to protect from rust, use mineral oil if the knife is used on food. Otherwise, Tuff Glide, Ren wax or other treatments can be used.
