Tactical knife sharpening

[tcsnake]

I'll keep this short:

I have a tactical knife, I would like a reverse blade sharpened out along the spine, where would I be able to have such work done? how much would it cost?

The Knife is a CRKT Elishewitz

When I read the title I thought you were talking about sharpening a knife while wearing camoflague and face paint and hiding under a log. Ok sorry, I'll go now since I have nothing of value to add.

California Knife Law

I would read though your state knife laws. Making it a dagger may seriously limit it uses.

Tim,

I'm not sure what you're asking. Do you want the back sharpened all the way to the tip as Jim has inferred?

If so, that's not going to just be sharpening. First you have to grind the edge to the tip and then sharpen it. That's probably going to be prohibitively expensive since it will have to be done very slowly to avoid drawing the temper out and leaving your tip soft. I'd also guess it would cost ~$100 for someone to take the time and trouble to do it.

What you want done will probably cost 70-90$, and turn a 100$ knive into a 50$ one.

Ignoring CA law (I can do that), you probably would be much better off to invest in a weapon that is what you want in the beginning.

I am no blade expert, but have owned several thousand blades of various sorts (retired dealer).

RE:

Im perfectly aware of our dagger/ dirk laws in CA, this knife will not be carried on my person, and is thus legal I have contacted the DOJ on several occasions and they inform me that owning a dagger, buying a dagger, and importing a dagger are all legal ventures. oddly enough the buying of a dagger would require that you carry it outside of the store to get it home (which is in fact illegal)??? odd... I guess that makes me a felon.

 

[hso]

In a box or case it won't constitute "carry".

 

[tcsnake]

and yes, the goal is to have made into a pure dagger, and then done up in a OD green Paracord wrap.

 

[conw]

Why not just buy a dagger?

 

[tcsnake]

Because most daggers out there are china-made crap, with the exception of the Fairbarn Applegate models, and even those have handles too fat for my smaller hands. No, this will be a custom one of a kind piece without the insane price tag of a Chris reeve, or a T.O.P.S model.

To OP:
I admire you for sticking with what you want.

I brought home, from a trip my uncle paid for, a couple of Gerbers Mark II with rib spreader blades. They are absolutely beautiful, even though well used. I can empathize with the desire for a custom dagger.

 

[tcsnake]

@bobelek yes I have had my eye on the Gerber mark II, amazing knife.
the blade is a tad too long and skinny and the handle is rounded which is good for some, just not my cup-o-tea. the mark II is a decided thruster, with little emphasis on the forward slashing attack, as it effectively lacks the belly to do so.

tcscake,

Expensive maybe, but "insane"? Hardly. Both manufacturers make much better knives than CRKT (and I love CRKT's knives). Twice as good for twice the price isn't uncalled for. If it's insane to pay that much for a wall hanger, well, sure. But both CR and T.O.P.S. make knives to be use and charge for them.

You have to understand our confusion on spending $100 to modify a knife with an MSRP of $160 that you can find for $80. You end up with a customized production knife.

OTOH, If you really want a double edged version of this knife and don't want to plunk down the hundreds for a custom from the designer, I get that. (being a knife knut there are all sorts of things I've done that only another knife knut would understand)

Probably the best thing to do is look for a local machine shop that can CNC the grind out to the tip. Once they've extended the grind to the tip you'll have better luck finding a commercial knife sharpener to finish the edge for you.

Tom Krein has done some nice work re-profiling/re-grinding knives to fit what customers want. I would check with him.

One of my favorites is my C.S. OSS... but they don't make it in Carbon anymore, so I don't know

 

[Smokey Joe]

To the advisors...

of the OP, saying that he'll have to spend $$ to have his knife re-profiled: Now, I'm no knife knut (though I've made a couple, and am good at hand-sharpening) but why couldn't the OP re-profile his own knife by putting it in a vise and using a file to do the necessary grinding?

A file goes slow enough he would never hurt the temper of the steel, and he could watch the progress of what he's doing. He'd have to be careful, of course, but you always have to be careful working near a sharp edge.

Not wishing to be a smart-a$$ here, just asking a serious question. And putting my own ignorance on display.

 

[7X57chilmau]

Smokey, if his knife blade is properly hardened and tempered, I'd expect it to wear out a dozen or so files before he achieved the results he wants. I made a dagger recently, and did all the blade shaping by hand with files.... But before I did the heat treat. I verified the success of the HT by trying the file on the blade... This time it "skated" rather than cut, showing that the steel was now hardened.

There are ways to do this at home, but none are easy, and most are more expensive than having someone do it for you... I could think of a few, but the potential for screwups and personal injury are high...

The OP needs to find someone well versed in the use of a belt grinder...

[hso]

It won't hurt the temper that way and if he's comfortable doing it there's not a thing against it.

 

[Smokey Joe]

Hmmmmm...

Interesting responses, to say the least! About how hard is the ordinary mill bastard file, on the Rockwell scale?

As opposed to a HT'd blade which will be in the 56 to 61 range?

 

[7X57chilmau]

Files tend to be in the low 60's... 61-64 maybe.

Might do the job on mid 50's RC knives... Wouldn't be my choice!

annealed, as I file blades, 1095 (for instance) is about RC40....

File wont touch a knife. It better skate across, especially if you spent 100 plus on it. If file does bite. the blade is differently treated and the spline or top edge will not be hard enough to hold an edge.

OK, I have watch this thread for over a week. You all sound like couple of Mall ninja talking about what they are going to do to do with their 5 dollar knife purchase. First off you are going to ruin all of the value of 150.00 knife. You truly are going to make it a 5.00 knife. You cant carry it any place. so it just becomes a letter opener on a desk. That to me is the real crime, taking a workable knife worth 150.00 and ruining it.

I am sorry if this comes off as little offensive to some. This is just an opinion should be just taking as such.

 

[hso]

Ohhhh, it'll take a while and and a barrel of elbow grease to file it by hand. No doubt about that.

The blade should be through hardened. No differential heat treat on a factory knife like this.

I don't think it's reasonable, but folks do all sorts of things I don't understand and I'm pretty sure I do things others don't think are reasonable (What "sane" person has blades round that cost more than most guns?).

 

[7X57chilmau]

Sanity and hobbies are on opposite ends of the brain.... LOL.

 

[ChaoSS]

BTK, you yourself just posted the CA knife laws, why are you trying to say that a double sided knife is any different than a single edged knife, and that it is illegal to manufacture a dagger in CA?


Let me quote back the relevant sections of the law here:

12020. (a) Any person in this state who does any of the following
is punishable by imprisonment in a county jail not exceeding one year
or in the state prison:

(1) Manufactures or causes to be manufactured, imports into the
state, keeps for sale, or offers or exposes for sale, or who gives,
lends, or possesses... any ballistic knife, any nunchaku, any metal
knuckles, any belt buckle knife, any leaded cane, any shuriken,
any lipstick case knife, any cane sword, any shobi-zue, any air gauge
knife, any writing pen knife, or any instrument or weapon
of the kind commonly known as a blackjack, slungshot, billy,
sandclub, sap, or sandbag... [see below for definitions]

That's the part about it being illegal to manufacture, sell, possess, etc, note, no mention of a dirk or dagger.

(4) Carries concealed upon his or her person any dirk or dagger.
see (32)(e)(24) below, for definitions.

That's the only restriction on dirks and daggers. You can't conceal them. You can carry them though.

(24) As used in this section, a "dirk" or "dagger" means a knife
or other instrument with or without a handguard that is capable of
ready use as a stabbing weapon that may inflict great bodily injury
or death. A nonlocking folding knife, a folding knife that is not
prohibited by Section 653k, or a pocketknife is capable of ready use
as a stabbing weapon that may inflict great bodily injury or death
only if the blade of the knife is exposed and locked into position.
(24)(d) Knives carried in sheaths which are worn openly suspended from
the waist of the wearer are not concealed within the meaning of this
section.

There's the definition of a dirk or dagger. His knife is already a dirk or dagger by CA law, adding a second edge to the other side does absolutely nothing to this knife in the legal sense.
