TGLB variances

[David Brown]

Hi Everybody,

I traded my first TGLB comp finish off in Dec (because I ordered the Walking Dead version i.e. stripped w/tan and black g-10)

Now it had canvas scales and felt a lot lighter, I just chalked it up to G-10 is heavier than canvas.

I was wrong

so we did a little weighing and measuring last weekend.

Here are the results;

Weight thickness of Blade

1st Gen TG 19.9 oz .25"
TG LB canv coated blade 16.2 oz .255"
TG LB Canv comp finish 1st gen 14.2 oz .255"
TG LB G-10 Comp Finish 16.7 oz .255"
TG LB Canv Comp Fin 2nd gen 16.9 oz .252"


Now is that weird or what ?

I weighed them over and over.

The only thing I can tell is the 1st gen Comp fin canvas one is ground a bit more, but 2 oz seams like a lot.
I am not complaining as I love my super super light Brigade TG, just thought it interesting.

pics later

anyone else weigh theirs ?

Pics so it happened

I don't have a good grasp on how much an ounce or a pound is, but 14.2 is about 89% of 16.2, and that should be visually noticeable I'd think. Maybe there's some inconsistency in the density of the steels somewhere? Are their centers of balance at the same spot?

I guess you're assuming then that these blades are fully done on a CNC and no operation is done by hand? You could always go around measuring parts to see what is what. My guess would have been that where the handle scales meet the blade tang they'd have been ground flush by hand which would induce variability in mass. You could always measure and get back to us. I'd not be particularly phased though quite frankly.

*edit*

Just for you uyotg 2 ounces is about 1.5 slices of bread, or all the beef in an entire Taco Bell Restaurant after they just got in their food order.

I'm going to venture a guess that it is the wear on the cutting/grinding parts on the cnc machine itself.

 

[Last Visible Canary]

anyone have a micrometer/caliper set to check the edges and web thickness? If you take the internal webbing from 3/32" to 1/32" you'd drop a lot of weight in the handle. or taking the edge thickness from .025 to .040 with a slightly lower (thicker) saber grind. Or a larger radius concave grind (flatter).

 

[David Brown]

Wow, I just thought it was strange.


Over all they look the same.
The lighter one seams to be deeper hollow ground just a bit.
I did measure the thickness at the scales and height of the scales
Like I said they look the same and the telling thing is they fit in the same molded sheath.
The grind is a little higher up on the lighter one


Oh I did weigh a couple slices of bread and 2 normal cheap store brand sliced white bread weigh 1.9 oz so that was pretty close hunterseeker5, for what that's worth

I am curious if maybe under the scales one is milled out a little more than the other ?

 

[BluegrassGuy]

This got me curious, so I weighed my coated with canvas TGLB and it came in at 14.78 oz. My theory is that the grind is more thin than others because even after putting a 30* edge on it, there is not as much edge showing as pics I have seen of other TGLBs.

That is some funny stuff right there! half a taco went through my nose

Thanks, hunter. That doesn't seem like a lot at all, especially comparing the density of INFI to... uh... bread. I guess whether that 11% weight difference is noticeable or not depends on where there is steel missing--in the thickness is probably not so perceptible.

Also anyone notice the difference in Tan canvas's ?
Does it happen because the material is cut against the grain different ?

all three are new un-used handles

I prefer the color of one on the left most of all

 

[wacki]

That's a pretty big difference in tan canvas. I agree I like the left one the best as well.

The different patterns are because the cuts are made to different levels. On some scales, let's say you cut down just 0.18", sometimes you hit one color layer; on others, you might hit the other color. That's more noticeable with their G10 though, where you have black against some other bright color in easily distinguishable layers.

The big differences in colors here though are definitely more than just the cut. It's probably inconsistency in the canvas colors. One thing to note is that the colors in fabric look much more saturated once you start adding resin to it to make Micarta; however, I don't have enough experience to map out what colors end up looking like what when they're saturated, but I imagine it's pretty straightforward--the one on the left was much darker than the one on the right presaturation.
