I had the good fortune, once again, to visit the Survive! workshop recently. And once again, I was humbled by the graciousness of my hosts. I was lucky enough to have a great conversation, and I finally met the enigmatic “Christian.” I also met Murphy, (what a cool dog.) We shared a few laughs, I snuck a few peeks at the shop, and Guy was kind enough to show me and my friend the new spec GSO 4.1 (it was a sheath template non-heat-treated knife) but it was true to size. I must say, I’m a little mad at myself for not getting in on the pre-order for that! Ellie also showed us the new GSO 2.7 that Guy shared on Instagram. What a cool little knife. I am always amazed at how much is going on there. I’m not sure if they actually have lives outside of the shop. They are always so busy, but I think most of you had figured that out.

Nearing the end of our visit, Guy and Ellie surprised us with a Pre-Production sample GSO 4.7 Mystery steel knife. Guy gave us specific instructions to use the Heck out of it, and let him know what we thought of the steel. To say the least I was stunned. I’m not a steel junkie. Neither is my friend. How could we possibly give an honest opinion of the steel? Nonetheless, Guy insisted that we give it a good workout and let him know. We said our goodbyes, and Thanks, then we headed back to our side of the Pass.

Not being sure of how to proceed, I looked at any review I could find. Of the reviews I found, none actually showed how this mystery steel performed. Course of action identified! We would compare it to a known quantity. We would sacrifice my GSO 5.1 in CPM20CV.

We decided to do our best to eliminate any variable that was possible. Both knives would perform the same tasks, with approximately the same materials. We would eliminate tasks that favored longer heavier blades, or smaller lighter blades, as that would not give an accurate representation of performance. We did our best to give a No BS true Head to Head comparison. We did NOT do anything that we considered to be “unrealistic use” in our testing, like dragging them behind a truck at 60 MPH or shooting them out of a cannon or pounding on them with a 16lb sledge hammer. We did however, use them much harder than I would have under any normal circumstances. Here You go:



This test required a trip down to the camp. Unfortunately it had been raining for the last few days and the morning of the test day, so everything was wet. You can see the difference on the ground between that which was covered by the lean-to and that which was not:





The Challengers:





The solution to starting a fire in N. Idaho when everything is wet, is to find some Fatwood or Lighter Knot! We set about Processing it:






















For any of you that know, that amber gold will dull the edge of a knife quickly. Fortunately, both the 4.7 mystery steel and 5.1 were up to the task, but both the blades were sticky from all that pitch.

Once we had our fire starting magic covered, we needed firewood. It’s just as well, maybe beating it through some regular wood would clean off the pitch:



















Whoa! Just what the heck are you thinking? My friend said: “I’m going to give it a workout.” Before I could say no, he beat on the 4.7 like it was a seven dollar machete:




Holy Crap! He tried to break it by torqueing it while it was buried in the wood. The wood popped in half!






He then informed me that my 5.1 was next. Sorry fellas. No pics because I couldn’t watch.

After I thought he would break both knives, on several different occasions, we had a nice little pile of firewood. But I’d just like to know why a fella that was an Eagle Scout would do that to a knife. I mean, what happened to the old saying: “Take care of your knife and it will take care of you?”




A strike from the ferro rod and the fatwood shavings burned like torch. A few minutes later, and we had an established fire despite the rainy wet conditions:




After we had a developed coal bed, I was hungry. What better to wash away the awful thoughts of how my so called “friend” abused my knife, than BACON! Never mind the Gratuitous shot of the Survive! knives in the background.



MMMmmm….Fatman Fuel! Yum!

Needed something to wash it down with. Pine needle tea, and a good smoke!










After telling lies for a while, our fire had burned down, our bacon and tea were gone, it was time to call it a day. We cleaned up the camp, put the fire completely out, and packed up. Curious, I decided to inspect the damage to the knives. There was none. No edge deformation, no chipping, no burs. I wiped the blades on my jeans, and they both were able to shave hair from my arm. Quite easily at that.








I don’t understand it. After the unspeakable things he did to those poor knives, they both still shave. ????? What kind of wizardry did Guy use in making these knives? I can’t really say, but I can say , all kidding aside, I am astounded. Seriously, I never imagined that any knife would go through what these went through, and still be able to shave. I am Truly Impressed!


Now is a good time to note that I took over 400 pictures of the torture, but I had to narrow it down to a manageable number to post. Also, everything the 4.7 was subjected to, the 5.1 had to endure too; but since the primary focus was on the 4.7, I opted for more pics of it.


Sadly, I feel we failed to achieve our goal of giving proper feedback on the mystery steel’s performance. After all that we put it through, it still shaves. The only thing I can offer is that it is impressive. It holds up to abuse at least as good as the CPM20CV does, but who can really tell if it does better? Certainly not I.



A Glamour shot of the 4.7:




A not so Glamour shot:




After a little rubbing alcohol to clean off the nastiness:





I am also surprised with the Coating on the 4.7 I can’t believe that there is any left on the blade let alone being fully intact with just rub marks.


While I can offer no insight as to the steel, nor quantify its edge holding properties, I can say you should give it a shot. I seriously doubt that you'll be disappointed.

Lastly, I’d like to Thank Guy and Ellie for this fantastic opportunity to try out something new. It has been cool. I’d also like to Thank my woodsbumming partner “HamHock” for all of his effort to make this outing and testing session possible.

'Bout time you joined the Forum!
Thank you, I couldn't have done it without you!

Thank you Junkyard (HamHock as well), what a great review! I have one on order and cant wait to try it out for myself!!
I am curious to see how hard/easy this knife is to maintain the edge or re-sharpen...but I have yet to see someone dull this knife!
 
Very nice write-up. If I didn't have a tester 4.7 of my own, I'd be jealous. I am, however, jealous of your camp....
 
Nice review and great pics!
Look forward to the reveal of the steel :thumbup:
 
Great review Junkyard and HamHock! It's great to see that the SK-4.7 and your 20cv can handle a whooping and still shave after.
 
Great review Junkyard....You had my attention with the Bacon!
Big bad knot in that wood too,Impressive!
Really don't need a 4.7,but then...
 
Great insight and thanks for the great comparison review. Your guys camp is pretty cool by the way. I can attest that the new 5.1 is a champ. I beat and pryed on mine like I did my old 4.1 and it didnt phase it a bit.
 
Awesome review. Am happy to know the the 5.1 20CV is just as tough [emoji106]

Really cool review! I really enjoy reading threads like this, thank you guys for sharing!
 
I love this picture!!!!!!



Junkyard, thank you sir for taking time to snap the pictures and give the knives a good workout. Any blade battoned through those kind of knots is a test. Welcome to the forum Hamhock!
