Knife advice for odd use...

Hiya folks, I have some odd parameters and am looking for some suggestions. My wife is the head grower in a wholesale greenhouse growing annuals and perennials. One of the tasks she has to perform is dividing plants, which involves cutting the root system of a plant in half to make two smaller plants. Soo... in discussion with her, I've identified some needs regarding this knife.

1. relatively pointy, so it can be worked in between the roots/stems of the plants

2. relatively long, so it can be used to divide larger plants (I'm thinking at least an 8" blade)

3. Fairly sturdy because it might be used to pry a bit on stubborn plants

4. No sharpened swedge, nor a thinned one. One of the ways to split a stubborn plant is to push the knife through, then push down with one hand on the handle and the other on the end of the blade.

5. Relatively rust-resistant steel, since this is a "workin' knife". Also fairly wear resistant, as it will be cutting through soil.

6. Available new, or easily found on the open market.

She's used a variety of knives in the past, from an assortment of old kitchen knives (not very sturdy, ends are kind of thin to push on), to my EK bowie (blade was a little short, narrowed swedge was uncomfortable to push down on). What we're currently eyeing would probably be WAY overkill, and that's a Busse Fusion Battle Mistress. Others in the past have recommended various Swamp Rat offerings, but those aren't available right now, and quite frankly, I don't feel like spending the "collectable" premium on the used market. I had high hopes for the Fallkniven A2, but the swedge took it out of the running.

Quick note about my wife... she's 5'9" and does a lot of physical work, so she's not a little dainty girly-girl. In other words, don't fail to suggest a knife because it's "not a girl knife". :D (I once tried to get some advice for buying her a folder in a local knife shop. I told the guy that she was almost my height, what she did for a living, and that she really liked my AFCK, but he kept suggesting tiny little brightly-colored knives. Quite frustrating.)

Thanks in advance!
 
Ranger knives, RD9? 9" blade, not too expensive, thick blade to push on, should hold an edge well and handle any abuse. i think 5160 steel, comfortable handle too.
 
Check out the becker knife and tool line. It sounds like the bk7 or 9 would be great for this job.:thumbup:
 
The Ranger and Beckers are possibly in the running. The handles on the Becker look pretty blocky, though.

Japanese kitchen knife is TOO pointy, and narrows down a lot near the tip. She would probably break it pretty quickly. :)

The Opinel is ... interesting, but I think I'm looking for a fixed blade for this application. Don't want to be cleaning dirt out of a hinge and lock.

Thanks! Keep 'em coming!
 
Do you really need the blade thickness of the RD-9 or or the Becker blades? I would think something thinner would be a better choice for cutting up plant's and dirt. How about a Machete or something similer.
 
What kind of plants are these, do they have woody stems?

I have an RD6 I'm putting an edge on now, full flat ground model. It's very thick along it's length, and not pointy. If she needs something this tough (3/16" 5160), then I would suggest ordering directly from the maker and asking him to thin out the edge, which I've read he does quite willingly. Mine is still almost 2 mm thick behind the edge at the tip, which I had to grind in.
 
Sounds like a knife that's gonna need to take a decent beating.

I'd consider some of the offerings from ragweedforge.com. Namely this one from the Frosts/Mora section:

http://www.ragweedforge.com/c-173.jpg

can get it with a 7'' blade or an 8 3/4'' blade. thin, carbon steel, sharp as hell, pointy, and for a workin' knife that won't break the bank $36 aint bad.

That failing, maybe you could track down an older Becker #5. Sounds like it would fit your parameters as well.

I've also had good luck with a Helle Lapplander. big, thin blade, sharp as hell, and even stainless. as a bonus, if she's working around people it's not very intimidating for a knife it's sze.

Just some thoughts. *shrug*

happy huntin'!
 
Jim70 : I hadn't thought about a machete... I could be wrong, but I understand that they are typically made from a softer steel. Personally, I would prefer something more wear-resistant, as I'm likely to be the one doing all the sharpening. I don't know that I want to file it down every night.

TheKnifeCollector : I had looked at the Bark River knives, but didn't see anything with an 8" blade except for the Golok, which she didn't like the looks of. Is there a large knife that I'm missing in their line-up?

Hardheart : They grow a wide variety of perennials, and from what I've seen some of them do have woody stems/roots. Thanks for the advice on ordering straight from the maker... I'll keep that in mind when we choose what we want.

RunsWithScissors : I like the look (and definitely the price) of some of those scandinavian blades, but damn, are they thin! I'd worry about the blade breaking if she were trying to power it through a root ball and it hit something hard. Can they stand up to that? (This is not a "finesse" job, more of a "brute strength" job.)

I've horsed some of my Moras pretty hard. I've deliberately pounded them through red oak blocks with a framing hammer trying to break them, with no success, I've bent them thrown them, etc. (they're the only knives I can afford to torture test...:o Might be worth a try. I'm thinkin' about one for my canoe myself.
 
I think a Mora would probably be the right tool for the job, it they're long enough for what you need to do. A CS Bushman might do the trick as well, the blade on those is pretty thin and they're carbon steel so relatively tough.

My favorite knife for heavy-duty outdoor work is the KaBar "cutlass/machete". It's survived almost cartoonish levels of abuse and is still going strong. I don't personally recommend using expensive knives for real dirty outdoor work, but if you have the money, a Busse or Swamp Rat cuts the hell out of anything you put in front of it. They might be a tad thick, though.

If you were considering a Busse, but don't have the cash, a Ka-Bar cutlass like mine is pretty close in blade shape and size to a Battle Mistress. And from experience I can vouch for it's durability and edge retention. I've used mine so much that the black is almost all worn off the blade, and it still has most of the factory edge on it (I had to touch up part of it where an idiot friend chipped the blade on a rock) You can get this knife for under $50.
 
I would also check out the ontario rat line. These are tough rugger knives that have no swedge, not too thick and not too thin. Deffinetly give thema look :thumbup:

You may want to try a 1969 cetme bayonet. They are easy to find on the surplus market, inexpensive, rugged and cheap. They also take a nice edge.

I wouldn't bother with anything too elaborate. Working in soil will dull any knife quickly, so you are better off with something that can be readily sharpened, which means avoid heavily alloyed stainless steels.

For inexpensive, old bayonets and kukri knives are a deal that may be worth trying.

I've given both to aquaintances who did garden work (some on a rather large scale for a "hobby") and they reported that they liked them.
 
I would take a look at a Felco Folding Saw. http://www.felcostore.com/order1.jsp?code=F600

My son, who is doing a Horticultural Internship at the Cincinnati Zoo carries one of these constantly. All of the professional horticulturalists and maintenance staff carry this as well as other Felco pruners and tools. They are a Swiss Company and considered the Cadillac of the industry.

Reminds me of a giant Spyderco:D
