POLL: SURVIVE! EDC-4 Preorder Promotion. Would you participate?

Guy,
Can you do a video of the same knife tip test using an M-390 variant of the GSO-4.1 as you did with the 3V? I am not very familiar with M-390. I bought M-390 with the intention of using it for hunting but if it's my primary fixed blade, I have to know what I can/cannot do with it...

Here is a quick video I made prying with the M390 GSO-4.1:

Very nice. You didn't go to the extent Guy did but a reasonable scenario, much more likely anyway. Your review was very good and much appreciated, very informative with some intellect behind it.

Yeah, no WAY I was repelling down a cliff-face, however short Since the purpose was to pry off a chunk of wood, I saw no reason to attempt to flex the blade to the limits of elastic deformation, instead flexing only until I considered the force excessive, then withdrawing the knife and re-inserting it into the wood at another point until the grains of the wood let loose. I didn't want to lay my entire weight into the blade only to have the wood fracture suddenly and send the knife flipping out with the potential to do serious harm!

It may not be evident in the video, but the knife flexed quite a bit with the leverage, much more so than the Bravo 1 would have due to the amount of support material (evident in the cross-section). Regarding the material properties of these steels, however, their lateral tensile strength (UTS) doesn't differ much at the same relative hardness. A-2, CPM-3V, M390 - at the same cross-sectional area and level of integrity, all three should be able to handle about the same amount of lateral force prior to deformation or fracture. Impact toughness (where A2 and CPM-3V are superior) doesn't factor in. The hardness and matrix composition inform where the elastic limit is and how the material will respond thereafter, and all of these will have been back-tempered to relieve stress in the matrix. What this means is that the CPM-3V blade is not superior to the M390 blade in these conditions. What Guy did with the CPM-3V he can do with the M390. Until you bring impact shock into the scenario, CPM-3V will not show superiority. But if anyone has information to the contrary, please correct me on that.

So why did Guy's GSO-4.1 perform better than the BG knife? A few factors may be involved.
1) Cross-sectional area of the BG knife's tip (hollow-ground, iirc) is probably thinner than the GSO which is fairly robust. This is the simplest explanation and is easy to test (if someone has a BG knife on hand). The Gerber LMF & Prodigy would perform better.
2) Steel quality - It would be interesting to see how much force was required to bend the BG knife's tip prior to fracture or if it gave way without significant bend. If the latter is the case, it is possible that the matrix was either too hard (stressed) or of low integrity, i.e. inclusions or micro fractures already present that propagated upon stress.

As a side note, Gerber's lifetime warranty will probably cover that BG knife. *shrug*

Today I received my GSO-4.1. The UPS couldn't find my address and I had to call them 3 times. I live in the middle of a normal sized city. They said my address wasn't in the navi system. So I had to chase the UPS truck for 20 kilometers to get my 4.1! What a crazy day.
But it payed off when I opened the package and saw my beauty. Fit and finish are great and it came crazy sharp out of the box! The only thing I will change on this knife is the handle. Or I should say the color of the handle. I'm going to try to dye it whit black RIT dye but I will also buy some camo color scales from Guy. Thanks Guy!

Here are some pictures:

When did the 4.1 in CPM-3V get sold out?

 

[gentemanndvm]

mine came today:




nice surprise, since i had only ordered 1.



Guy,
email inbound as soon as i track it down. pretty sure that you didn't send me two extra knives for free just because i'm so awesome. i AM that awesome. seriously. i just don't think you sent me free knives because of it. we've never met, and my awesome-factor-by-reputation-alone is probably only worth, like, 1 free $170 knife. plus maybe 4 beers. if we had met before, i'd totally understand the 2 extra free knives. but we haven't. so probably a mistake....









eta: Guy, email sent via BF email system.

 

[Thomas Linton]

HEY! You got my free knife.

Ok so I didn't love how high the clip made the knife ride, so I made a leather drop clip.

Finally opened up my GSO 4.1 today! Got it in the mail earlier this week. Only a minor problem.

I ordered black micarta and a green sheath. It looks like I received green micarta and a black sheath.

I think I actually like the green micarta and black sheath better, so I'm perfectly happy with what I received.

Its gonna be hard to top this pair

looks good man, i think i'm going to do the same .just wondering, does the handle lean out away from you with the less rigid clip or does it balance out okay?

I was reading your mind. lol. No, honestly I realize now that the export my old web team did for me of all my website info had a few glitches. To anyone affected, sorry about that. Well, except you gentemanndvm. Your mistake worked out pretty great. lol If anyone has any huge issues, please just shoot me an email to let me know and I'll make it right. Guy@SurviveKnives.com

 

[Tinbanger]

Stickinc1 the handle did tend to lean away from me, so I had to wrap some ranger bands around the top of the sheath. Works great and doesn't look bad either.

 

[Ruudr]

Just a little update. I dyed the handles of my knife with RIT dye black. The standard color was natural micarta. I think it came out very well!

 

[loonybin]

My GSO-4.1 showed up a day earlier than UPS was predicting. Gotta be happy about that!
This thing is hair-shaving sharp right out of the box. The heft is great, and it balances very well. This is going to be my hunting knife, so I need something that is visible at dusk when I set it down while gutting a deer -- hence blaze orange handles. I did not get in on the preorder, so I paid full price. This is the most I have ever spent on a knife, and it is worth every penny.

I know some view the markings on the spine in a negative light, but personally I think they look pretty darn cool!

 

[dwarthog]

Mine arrived via UPS yesterday.

Despite all of the angst associated with the waits/delays/issues etc., I'm pleased with my purchase.

It's a very nice package, well done Guy!

 

[underdog406]

Yep, sure am. In the next few weeks you should begin seeing optional handle scales. Just need some time to recover from getting all of these out. lol We are finally up to date on all GSO-4.1 orders. If you are looking for extra sheaths, you can actually order any color you like directly from Kiah.

Got it, thanks for the heads up, will also keep a close eye on when the scales become available.

Cheers.

hey all,

you saw my post up above where i got a couple extra knives by accident. guy was ridiculously generous and offered to let me keep one for my trouble. don't need 2, so we decided to do a giveaway to someone who'd use it.
any deployed soldier is eligible.

here's the thread:

if you're overseas or know anyone who is who'd like the knife, check out the giveaway. only takes a pic.

 

[SURVIVE!]

That's pretty darned cool looking. Let us know how it holds up over time. I'm curious how deep the dye penetrated.

Just a little update. I dyed the handles of my knife with RIT dye black. The standard color was natural micarta. I think it came out very well!
