Can you use a rock to sharpen a knife?

Well Cliff are you willing to take that challenge? With all your infinite physics knowledge I figure you should be able to kick all these primitive tribes ass with your super-sharp high-tech scientific blades you test in your backyard. :)

If you decide to then I'll place my money on the young newfie for the first go-round. I love to bet on the underdog ;)

Oh...back to your orginal post. A lot of the tribes that I have visted STILL start fire by primitve methods in very wet environments. I've hauled a lot of folks down there with bic lighters and trioxane and they STILL could not get a fire going. Yep, ain't science a helluva lot better than field practice and good old common horse sense? Bottom line to this WHOLE thread is surviving when and where high-tech science may not be available. I say use a bic lighter when you have it. Ain't science wonderful, but you will be royally screwed when you don't have it anymore and your life depends on fire.

I will agree that science has given man advantages. I love my color TV set and my Direct TV with the Playboy channel inside my double-wide mobile home. I love my beer cold from that new-fangled plug-in ice box I have. And that microwave just flat out impresses the **** out of me when I put one of those TV dinners inside because that new Tv never did cook them right, but it ain't science that keeps my ass from getting bit by a snake while walking through the woods without high-tech scientific snake gators, or being able to hunt and capture alligators long enough to swallow you without a damn knife or gun. It's learned knowledge from the field that does this. Something you will never learn in a graduate school. Oh it might have had a part of the reason but the bottom line is learned knowledge from the field has kept me going. I can look at a book on snakes and even have a college professor teach a class on them but it still does not present all the variable that will be present in the real world. That comes from long-term experience in the field. Same with knives AND sharpening.

I have no problem with science but I do I have a problem with educated idiots that don't have the common sense to go along with it. In the long run of wilderness survival, common sense and field practice will do you better than book knowledge of why an edge works better at this angle or why perfect sharpening is the key to best results. Why not build your shelter with what's available instead of making sure everything is scientifically perfect before you start? Seems to me you would be a time waster in the field trying to get everything perfect while the sun's sinking.

Science is great on the initial design or construction of a knife, but once you get in the field for extended periods you go with what you have and fit yourself to the environment instead of trying to fit the environment to you.

I've hauled high-tech sharpening gear and knives to these people. They still do a better job with what they have both in the knife department AND in sharpening.

Anytime you're ready amigo I'll take you on a knife using paradise vacation. Who knows, even you might learn something.

Cliff and Jeff,
Despite the bickering you guys are not really far apart. You are both writing that science can be good, but needs to be tempered with field experience.
You are both advocating possessing the knowledge to do things in an improvised fashion, if the proper tools are not available.

Stay Safe,
Chad

Victorinox Rules !!!!!!!!!!!!!!!
 
Well, I sharpened a knife on a knife this weekend!:p :p :p

Jeff mi amigo! Had a ball at Blade, and you are really into a party pooper! :D :D

Can you sharpena knife ona rock? Fckin A! Is it science, only if you want it to be.
 
Senor Rob,

Good seeing you again also. Ok, I admit...I'm a candy ass when it comes to beer. One hangover a weekend is enough for me. Too bad Blues wasn't there this year for our Ruby's party ;)

BTW: Will Fennell called today and was bragging on those new blades and that new steel you're doing. Said the little after-Blade testing on the farm impressed a lot of folks. Keep it up brother!

I suppose there ahve been more ideas and good designs come off the Fennell farm after the Blade show than anywhere else.

Common sense is taking common knowledge and common reasoning and coming up with practical solutions for your problems. The problem with common sense is when you get outside of the region where your common knowledge represents your surroundings. For general survival away from your native habitat it is best if you have systematically studied and practised survival techniques (in essence made a science of survival) or have a very broad knowledge and experience with how the world works in its basics. Many of the people with a broad understanding of how the world works are experimental scientists.

If you dropped an Amazonian native into the arctic or an Eskimo into the Amazon they would probably not last as long as either Jeff Randall or Cliff Stamp would. A survival scientist and an experimental physicist would both have better ideas for how to adapt their environment to their needs by way of building effective shelters and improvised clothing. Given unfamiliar materials to work with, a broad systematic (or scientific) knowledge of how to convert energy into heat will give you more ways to create fire where necessary. A broad knowledge of diseases and nutrition can help you stay healthy. I see scientific knowledge and experience as always a plus. The only time knowledge is a big disadvantage is when you are a fool who can't prioritize more or less important things. That kind of fool is hopeless (and all to common). Most of them aren't scientists. If your that big a fool you don't become a physicist (you become a mathematician).

Back to our primary topic. Yes you can sharpen blades on rocks. The easiest portable rocks to use are heavily weathered semicylindrical ones. It is uncommon to find a nice flat surface in the wilds. You may also look for a large erroded boulder. You don't have to be able to pick a rock up to hone a knife on it. If the rock is irregular it may be easier to use an edge-trailing stroke. Your edge can catch and get dinged on an irregular stone. You get the nicest edge if the rock is comparitively uniform in grit. If the rock is hard and fine grained it may tend to load up and get smooth as you worked. Rub it with sand and/or something like sandstone if it is a really great hone; otherwise go find another rock when this happens.

Experiment. Go collect various rocks and see how they work. Start with some old dull kitchen knives from a second-hand store then try a cheap hunting knife. I think you'll find simple carbon steel knives are the easiest.
 
While taking the course at the Army's Jungle Warfare Training Center in Panama years ago, the highest score in my cycle was made by an Innuit from Alaska.

On the other point just made, one doesn't become a physicist or anything else for that matter by taking college courses. Having worked in the sciences for many years myself, the greatest idiots I ever met were highly educated, but lacked any practical sense of how things actually worked and were devoid of the capacity to prioritize the relative importance of the issues that confronted them. I think that is exactly Jeff's point.
 
Since I don't shave with my knife or machete I don't use razor hones for knives. I have a few nice old hones and 40 or fifty other stones I use to sharpen woodcarving tools (that's how I make my living). I've been sharpening carving tools and woodworking tools of various description for about 30 years. I used the Jap stones for a while back in the early 80's when they became real popular with woodworkers and they did no better than Arkansas stones. The synthetic stones are ****. They wear very quickly and aren't worth replacing and the Japenese woodworker and I can do anything the other can do-- just different tools. The natural stones last much longer but are extremely oner hyped and over priced. (I don't know where they are priced at $1000) It is simple enough to establish a razor cutting edge on a cutting tool with an Arkansas stone which is much lower in price.

I disagree with Stiff Clamp on the grade of Arkansas stones being lowered. It hasn't. The grading system is as it has been for eons. I can still buy the same quality hard Arkansas stone today that I could 30 years ago but it will cost more because it's the supply that has diminished - not the quality.

I'll sharpen knives and machetes on concrete, rocks, sand and a board or whatever will cut the steel and develope a serviceable edge that will get the job done efficiently and safely. If I'm home then the belt sander works fine for machetes, India and Arkansas stones for knives and Arkansas stones for woodworking tools. If I'm in the wilderness I'll use anything that will cut steel. If it's a choice between carrying a bunch of sharpening stones or more food then the food wins. The little diamond hones are fine for little **** but useless for machetes and large knives.

My personnal viewpoint is that efficiency in the wilderness involves utilizing as much as you can from the environment so you don't have to lug extra **** around and are not dependant on something you might lose. Rocks and concrete are fine for sharpening in a wilderness environment. I'd say you could get hacked up just as efficiently with a rock-sharpened machete as one sharpened by Martin.:):)

****, didn't mean to go on so.:) Hell, it's too much trouble to go back and edit all this...

Sounds like me and Rob Simonich last Friday night during the unofficial Blade Show party at Ruby Tuesdays.
 
Friday night? Ahmmm... Seems like Saturday morning brought with it the regained capacity to realize important issues like aspirin, sleep, puking, etc, etc, although it is a while before the capacity to confront these issues is regained.:) Oh heck, did you not want me to say anything about that? Hey Jeff, I'm soooooo sorry.:) Your friend, Mike:)
 
These post-Tactical Knives magazine parties which end up at Ruby Tuesdays led by our fearless commandante Simonich are getting legendary, and maybe even out of hand. Strange how you can invite folks down to the party and they always seem to have something else to do ;)

I heard through the grapevine that we embarrassed another table of knife folks in there that night. Nawww not us. I think that's the reason Blues didn't show up this year.

I think we are, both geographically and what we are trying to achieve through our experimentation. I'm in search of the lowest common denominator in survival "science." In other words, what do people really need to know and understand in order to survive in the wilderness. Perfect edge angles, perfect steels, and perfect sharpening are not even in the ball park when it comes to this.

I love science and I love to understand "why" and even how to make things better, but when it gets down to the basics I always want to work with what's at hand instead of what's at home.

There are scientists that have both a real field practicality and higher learning mixed all in one. We have a moderator over on our forum named Hoodoo who is a college professor and also very practical when it comes to field use and getting down to basics. I appreciate that kind of knowledge. I don't appreciate "mightier than thou" attitudes because of some college degree, especially when the field experience is lacking. The best wilderness teachers I have found can't read a book or drive a car.

Jeff Clark :

A survival scientist and an experimental physicist would both have better ideas for how to adapt their environment to their needs by way of building effective shelters and improvised clothing.

Yes, but knowing how to do something, and being able to do it are two vastly different things. You can know exactly what to do, and be a very great teacher, and actually be unable to do it. Chop the legs off of a great track coach and they can still create a great runner but would not produce much of a time in the 100.

This of course has nothing to do with the original question, which was one on technique. Enough skill will allow an individual to easily overcome another with better tools or knowledge. However, transfer the tools and knowledge to the other person and they will gain from them.

It comes down to knowing how to maximize your abilities and make life easier for yourself. You can make due with anything with enough skill and raw physical ability. However, even experienced people die in such situations. Why would you want to not give yourself an advantage if you can.

Your knives will cut better, and last longer, reducing your physical effort, and thus fatigue and water and food requirements, if you use a quality hone rather than a rock. Just as if you use a quality knife vs a low grade one. Yes, of course knowing how to use both (or nothing) is an advantage. No one ever said otherwise. This is simply a straw man argument.

If the rock is irregular it may be easier to use an edge-trailing stroke. Your edge can catch and get dinged on an irregular stone.

On very sharp edges rocks you can use them as a sort of edge scraper. I started experimenting with this when I bought a small carbide sharpener which was designed to do this. You don't remove much metal, but you can restore heavily rolled, and lightly worn edges.

I have the honor and pleasure of calling Hoodoo one of my freinds. He is with out a doubt one of the finest men I know. I agree 100% that Hoodoo is a perfect example of a true outdoorsman. He has a vast amount of knowledge, both practical and acedemic, he is great with his hands and most importantly has an inquisitive mind and a huge ability to improvise and adapt.
Hoodoo is the kind of man I truly admire, growing up on a farm, sailing the world with the navy, a career in mechanics and a second one in acedamia. He is as well rounded as any man I have ever known. He is always willing to share his knowledge with others, and always treats people with kindness and respect. I have nothing but the absolutely highest regards for Hoodoo and am grateful that he is a member of of the online wilderness community.

Take care,
Chad
