Hi guys,

I am new to this forum and a total newbie when it comes to knives. I had been satisfied using only a Spyderco Endura for years and then last year I bought a Spyderco PM2 and that's about it. I have only been a flashlight guy and is not really into knives, that was until only last month I traded one of my flashlight for a Zero Tolerance 0560 Hinderer design and fell in love with the knife. I started reading up more and more here and finally bought a pre-owned but new INFI Ratmandu (a.k.a. Infidu) off the exchange for around $300-ish. The seller helped me send the Infidu over to Mashed Cat for the sheath to be done and it is currently in transit to me. While waiting for the Infidu to arrive, my friends have been talking to me about CPM-3V like it is the Holy Grail of all metals, and so out of curiosity I started looking into the Survive! sub forum. That's where I saw some links to some video reviews done on the GSO series of knives, mainly GSO 5, and I am impressed. The stress test, the ability to retain sharpness without much or any sharpening, corrosion resistance even though technically CPM-3V isn't rated to be stainless, and so on. I am all sold!

I looked up more and found that the GSO 7/7 is the only knife with model number not correlating to the length of the blade but rather the date when Guys' best friend had passed on. That touched me a lot, because I too lost my best friend to cancer whom I had spent more than a decade camping and hiking with. To cut the long story short, after much reading and YouTube videos on the GSO series and also knowing the 7/7 is going to be next on the production run, I jumped and pre-ordered the GSO 7/7 last night.

Ok, so here's the golden question. A friend of mine was telling me about the toughness of bamboo and how Japanese sword and knife makers uses bamboo for tests on the strength of the blade. If it doesn't chip the knife edge it is a fantastic blade. I once tried a sword belonging to my friend and sliced off a two inch thick bamboo in one stroke with no chip at all on the blade. The hardening and strengthening process on his sword was done by Keffeler and my friend swore by it. This got me thinking, all the videos I have seen does not portray any of the reviewers chopping up bamboos. So is the GSO series, especially the bigger ones like GSO 8 or 10 capable of chopping up bamboo? At least if not in a single stroke, but at least without chipping the edge? Some may think it is a redundant or silly question, and some may even wonder why would I need to chop up bamboo? But if you are in a place whereby what you have are mainly miles and miles of bamboo forest, can you survive? Would you be able to make shelter, or even a bamboo raft with a GSO knife? I know another friend with a Busse (can't recall which model) was having problems chopping through the bamboo that day although I can't recall if he chipped his Busse, but I don't think he did.

I know that most of you reading this may not have the luxury of trying the knife out on bamboos because there are mostly likely none in the geographical location where you are in, but I am just hoping that someone who have the experience can chime in?
 
Welcome to the forum bud!
You raise a good question and I'm curious to see what others have to say. I'm in SoCal so I can't help you out with the bamboo questions. This CPM 3V is amazing stuff and I'm sure you'll like it.
I think there are certain grind styles that'll chop better than others so that'll be a factor. Bamboo is nasty hard stuff also.

Thanks for the welcome!

As I had expected, it will be hard to find someone with the experience on bamboo, because bamboo is not growing everywhere. I know there are plenty in China. Lol!
 
You're welcome! I had to do a search on cutting bamboo and I found a video of a Kabar camp knife that was chopping through it with no problem. It looks like a Kukri style blade but it's pretty close in length with the 7/7.
 
Welcome to the forum! You'll find plenty of knife and flashlight nuts here.

As for bamboo I don't know of any here but there is good ole sugar cane. Not as tough but some similar properties to my knowledge. I'll see if I can get my hands on any and put my 3v to the test. I'm not sure that my 5.1 could carry enough momentum to carry it through in a slice but I'll see if I can.

Hell if I beat up the edge that bad I can send it back to Guy to fix. He does amazing on his blades. (I think silver was right, I believe he strops it on his majestic beard. Lol.)

I also have a 7/7 as well on the way I don't believe you'll be disappointed in your purchase. Don't hesitate to ask and if there's anything you wanna see the guys here don't typically buy S! just to set on a mantle, they by them for hard use. Check out all the videos you can in our video thread and if you wanna see other test I'm sure someone will put there blade in the mix.

Welcome to the club again bud. Enjoy.
 
Well for a "newbie" you've done some good research and really sought out some of the best brands for yourself.

My first reaction was to say "yeah! SURVIVE! 3v with Peters heat treat can cut through anything!!!!!!!!!!" but really I'm just left wishing I had the experience or the means to truly answer your question.

I thought it came up in a thread here where some Americans from the south of the country were comparing American hardwoods to some of the crazy woods our Australian friends encounter locally. I realize bamboo is entirely different, though.

This is a really practical question and I'll be watching for a good answer. Glad to have you here!
 
Not sure about bamboo but I know my SURVIVE!'s handle getting pounded through hickory and knots in seasoned oak with no problems. Can't think of anything much harder than those 2 that come from nature besides rocks.
 
I'm new to the forum. I have lived in Hawaii all my life and we have groves and groves of all kinds of bamboo growing wild here. Depending on the species they vary in diameter and wall thickness as well as density. The larger species diameter averages between 4 and 6 inches and wall thickness can be from 3/16s to over a half an inch. So there are numerous variables. I cut bamboo regularly for various reseons. From making fishing poles to construction of many different things. The blades I use vary from the cheap hardware store machetes to Busse's, Beckers, Cold Steel ESEE etc. I rarely have any chipping problems even with the cheapest of Blades as long as they are decent in sharpness. I must say that there are differences in edge holding ability with the various steels with the better steels out performing the lesser ones. The point I'm trying to get across is there is a technique involved with bamboo that can be more important than the blades. I find that cutting at an angle makes the cut much easier. Slicing through 2 to 3 inch diameters in one pass can be done quite successfully if the angle of the cut is correct. There is a sweet spot or angle to be had depending on the velocity of the chop. Perpendicular and your blade will likely bounce off. Too shallow of an angle and you will find your blade glancing off the bamboo. So it's not as cut and dry as one might think. Just food for thought. Aloha!

Hi guys, thanks for the replies! Greatly appreciated it! I apologize for coming up with such a hypothetical scenario and I hope no one would put their knives at risk just to prove a point to me that it cuts like butter on bamboo. I was posed this question about cutting through bamboos without damaging the cutting edge of the knife, and so I came up with the hypothetical survival scenario posted above. I most likely won't be having the need to cut bamboos with my GSO 7/7 when I receive it, but out of curiosity I might give it a try.
 
When I get free time I'll look for some cane stock and see what she does. Just like MoS I've pounded mine though lots of seasoned oak with no issues.
 
Well actually, Guy has tested some of the knives on bamboo. He has some family with a bamboo field. I believe we had a GSO-7/7 with us, which went through the live bamboo fine. It went through the dried bamboo ok, but it certainly dulled the edge quickly and the dry stuff splinters so it is a bit of a pain. I remember having the phone out for pictures and/or video so I will see if Guy still has any of that documentation still.

Having come from you, this is as great a news as all of us here could have received. Many thanks for that Ellie!
 
pjandyho and 808blade, welcome to the forum!

I worked my way up to 3v, sr101 and infi over some time. pjandyho, you have some fine steel coming sir.

Thanks for the welcome! I have my friends to thank for helping me gain my knowledge initially. Bladeforums did the rest of my education. Lol!
 
Hello 808, missed that yesterday but your 100% right. Technique is a huge factor in blade use.

Welcome to the sub forum.

The help from the bf community is phenomenal. Everyone I have meet here has been a huge help. And it looks like your friends got some good taste in blades.

Yes indeed. And because of that I foresee my dear wallet and I would need some counseling.
