OMFG IT R TEH INTARWEBZ HALP
You're both getting out of hand and equally so. HR's initial comments, while direct and blunt, were not particularly insulting...however since you chose to interpret them as such and respond by increasing the hostility in return...well, of course things will sto being nice.
I think we can leave it at that and move on.
I am interested in seeing what you might come up with and how it works out.

Cool it. Muffin, sorry to say but your idea of a knife with TILE GROUT for an edge is about the stupidest thing I have ever heard but that is MY OPINION AND EVERYONE CAN HAVE THEY'RE OWN. There are NO synthetic materials yet created that will hold any serviceable edge for a knife. Especially not tile grout. No one has done it because it is a terrible idea, so go ahead and be the first to do it and find out for yourself, no one is stopping you in fact you might prove evryone wrong (unlikely), just DON'T ARGUE THE FEASIBILITY OF IT HERE. You have said your piece, stated it is your time and materials so go right ahead, no need to argue uselessly about it with HR. You are new here, so please observe some self control until you get your feet wet, and remember, not everyone will always agree. Everyone here is friendly, some are a little direct and un-coddling, but all are very knowledgeable.

Hey sorry to jump late into this..............Muffin, as marc said welcome to SBG.........second it is true, we have zero tolerance for hostility...........I know finesse and subtlety are MIA somewhere around HR, but still he did not offend you on the first post, he just stated his opinion about the subject. Then things got heated and he did lashed at you. But, on the gashing and cutting terms; have you ever got cut with paper? Yes it stings and is bothersome, any substance with an edge might provide cutting potential if done at the right angle, however its ability to hold an edge, and that the edge has any kind of serviceability is another thing. As Sam said the only materials that hold a serviceable edge for cutting/other purposes is steel and by any rate only other kinds of metals might hold an edge, even if more crudely or for less time..............we are a friendly forum, with enough space to assure that not everyone must agree with a given statement..............so let's quit all this and welcome again.......
EDIT: Ceramic holds better edge than steel, but its uses are far *much emphasis on FAR* more limited and it is too brittle for tough jobs........

Since I love discussions I have to drop by , also I think it's interesting with syntethic materials as knifes. But first, just ignore HR as others have said, he is known to have an arrogant tone. And for your idea, just try it out, a knife does not need steel(wich is the best material for a blade) to be deadly. Many tribes in south america uses bamboo knifes, and they are sharp enough to shave hair, but they can't cut bone and they dont hold an edge well. But yes even bamboo can be used as a knife, in the stone age the humanoids used rocks as weapons/knifes and it worked so why not?

If you're going to argue that if something is "deadly", then it's a "functional" weapon, then there's still no point to synthetics like this.
Sharpen a pencil. There you go. It's sharp, and it can stab and kill. PLUS you can write with it.
There. I just made an equally effective "weapon"(since synthetic knives don't have the shock-absorption or edge-retention of steel, they are not tools) with a tiny fraction of the cost. Not to mention it's completely legal to carry and defend yourself with without fear of being arrested for carrying a concealed weapon(a folder is a tool #1, but a fiberglass dagger is essentially a shiv, and therefore only classifiable as a weapon).
It has nothing to do with being "arrogant". It has everything to do with the fact that it's been done before, and isn't effective enough to be worthwhile. He'd at least have something decent if he chose a STEEL edge over one made of fricking TILE GROUT... I understand he's trying to equate it to the edge-retention of ceramics, but ceramic knives are expensive and difficult to produce. It's not art-class clay or hardware store grout. They are made from specific recipes in controlled conditions. And even with all that, they are still brittle and easily broken. They are reserved for the kitchen.
Completely non-metallic "knives"(daggers, really...) are only suitable for use as thrusting weapons. They don't hold an edge, so they can't cut effectively for extended periods of time. I did mention the plastic lettuce-knife, which is fine as long as your cutting lettuce(not known for its toughness...).
Like I said, if one chooses STEEL for the edge, you'd have a more functional cutting tool. The main problem lies within finding an epoxy that is incredibly strong, yet doesn't cure brittle. Even a short knife blade needs the ability to flex. Without a flexible epoxy to bond the synthetic body to the steel edge, they will separate from use. To be honest, the only knife I've seen like this that appealed to me at all was (I think) a Mick Strider/Warren Thomas collaboration folder.
I wouldn't want a long knife, as I wouldn't trust it for chopping/batoning. Lighter isn't always better.

Aye, I agree with you HR, but if one looks back in history and looks at the present, there are knifes/daggers made of other materials than steel. Maybe the dundermuffin wants to make the best syntetic knife possible, each to his own. But I think most of us know that steel is the superior material for knives/daggers/swords.

I only wnated to Make it as Ive not worked with steel and wouldn't know the First thing about Making a steel knife, other than with an angle grinder. But with CF or Kevlar id know how to make something, without the Hassel of getting the small things wrong. plus if you do get something wrong with a mould or a product it can be easily fixed.

One interesting option, for a light cutting-duty knife, might be the carbon-fiber body, and a bronze edge.
Though maybe a tad difficult to locate, bronze doesn't really require the kind of heat-treating steel does. With a mere hammer and anvil, you can work-harden the edge down to a serviceable level. I wouldn't use it as a field-knife, but it would really be joining the old with the new in a way that hasn't been done before(literally, at all. It's always steel or Titanium...). At the very least, as an art-knife, the dark CF would contrast really well with a nice, shining bronze edge, IMHO. Plus, Jeroen Zuderwijk(sp?) over on SFI(or is he here, too?) is experienced in casting bronze blades, so there's a good person to talk to if the idea nibbles your jumblies.
Tile-grout might be hard and sharp, but it'll pop off like nothing, and then you'll have to replace the whole thing. Replacing a razorblade or X-acto is one thing, but manually resetting an edge like that is ridiculous.
It's this reason that knapped stone blades were abandoned for Copper(then bronze, Iron, and steel). Though stone blades are MUCH MUCH MUCH sharper than metals(literally, on a microscopic level you'd be FLOORED by the difference of a knapped flint to a modern, surgical scalpel), they are easily broken and require much more work, skill, and time to produce.
No matter how you go about it, I'd start with a folder-size blade first. Starting small is a good way of saving time while still remaining a good proof-of-concept. Then you don't end up with a foot-long waste of time if it doesn't work out the way you hope. Besides, making the handle for the folder is a whole new project. Even a plain, simple friction-folder offers a nice canvas for creativity and materials choices. Maybe a combination of hardwood and G10 scaled on a simple, steel liner.

Ive made panels before, and kevlar aircraft seats and parts... what i was thinking is scrap the original idea of making one mould, and just have a mould with a smooth side and an ugly side, like a panel, the mould would need to be pretty symetrical.. then id sand the ugly sides smooth,then just bond the two ugly sides together some how,maybe with epoxy cement and bolt them together at the handle, so you have two smooth clear black Cf sides. Then some how make a steele or bronze edge, or see if i can find someone in the near area who might be able to do it, umm which might be hard... im not sure if this is how warren thomas does it... but it could be worth a try.

Why don't you just lay it up onto either side of the steel core? If you rough-up the sides, and use epoxy-based resin (rather than polyester) it should bond, no?

Although this idea is not my cup of tea, I would really like to see the results. Therefor you have my unneeded support.

I don't really know how the molding of carbon fiber works but really you could just use a really thin hardened steel piece and then mold the carbon fibre over it. The steel would not need to be thicker than maybe 1-2mm. My idea is something like this: You maybe had something other in mind, but just my thought .

I'm not Fox news.. never claimed to be fair or balanced. The fact is , everybody got a pass... noone got in trouble , and all I did was unofficially ask to cool it out as I am not the mod in this section.... HR is correct , that argument has passed , and there is really no reason to try to stir up the trouble once again.... Both parties are behaving admirably.... BTW , welcome to SBG yourself.... feel free to PM me with any more complaints you may have. Hope you enjoy your time here , I look forward to interacting with you as a valuable contributing member of the community....
