Full height convex on early CGFSH?

Until today I thought the CGFSHs (.250") were simply a full height flat grind. Like CGs of other liniage, I would expect this to be this case across the board, ...typical, simple production techniques, right? Seems normal enough.

Well, I was looking at one of my .250" CGFSHs (also has an ergo logo'd blade) and it does have a full height convex:eek: The plung line terminates as it does on the Heavy Heart, but the blade profile continues past this point to the spine. Yes, the spine is also narrower than the area about 1/4"-3/8" below it (not including any dehorned portion).

Am I'm just late to the bus or this has already been discussed? Has anyone else noticed this or is it pretty common?
 
I think there might be something fishy about that CGFSH.

You should send it to me and I'll check it for you :D

I have owned a medium-numbered variety of FSH over the illness, and I have observed more than one FSH with the Ergo-Logo to have these very characteristics.

Later Heavy-Heart Logo FSH that I've owned all have a saber-grind that is easy/easier to discerne.

My Ergo-Logo and Heavy-Heart-Logo HOGFSH have been all flat grind.

This will be debated, but that is my observations. :D :thumbup:

Best regards,

Rat, my observations have also been the same but I was totally thrown off with this one. It's the first I've seen, other than my FSH desert Proto, which also has the same profile. IIRC, the coated protos from Blade '05 were all done by hand.

So the real question is, man or machine?;)
 
my FSH has the Fusion logo and also has a full convex grind. :thumbup:

And... the plunge line on mine also starts about 1/4" down from the spine.
You have to give it a hard look to see it though.

I remember this coming up before... 6 or 8 months ago.
IIRC... some are flat ground, and some are full convex.
but no pattern (ex all ego logos) could be found. :confused:
 
I had a standard CG FSH and it was actually about 2/3 - 3/4 convex ground. Almost like the saber-ground HHFSH, where the plunge line starts, the main grind is below that, just convex instead of flat. (Does that make sense? :confused:)
 
The early FSH's were ground with the CBT as I recall and were a little convexed. Very fine CBT like the SJTAC and AK and they might even have been touched up on a belt real fast.

Kev, I think you might have been absent from the Blade show where some of us had noted this on a FSH we had on hand. We put a business card against the grind and it was an obvious convex grind. As I understand it some of the early FSH were like that, maybe just the ones with the Ergo logo, but don't quote me on that.
 
I own both a FSH and a HHFSH and yes FSHs are convex ground. It is ground full height and most people just assume that it is flat ground when it fact it is Convexed. I have handled a few of them and they were all same. Even closeup pics of the ones I saw are also convexed.

Justabuyer had a thread a while back of a stripped FSH that he convexed with a polished edge. You can clearly see the horizontal machining marks and obvious rounded profile of the convex. I am pretty sure that all of the FSH are ground this way.

FYI, the SJTACs are also ground this way. It is just that the blade is more narrow making the convex less noticeble. Put a flat edge to it and the convex will be obvious.
 
The bottom two FSH's in the pic have a convex grind.

My HH's above illustrate the very different saber grind.
 
Z51, I also notice that yours has the Fusion logo. Which logo is on the Snake & camo one, it's hard to tell from the pic.

Fusion logo on that one also.

Unfortunately, I don't own the bottom black/black anymore.
 
Well.......

They are just kinda round where the others are kinda flat.
