Hi everyone,
I'm considering making a wooden sheath for a blade that i'm finishing. I figure that i can dremel/router the profile of the blade on two pieces of wood then pin/glue the two halves together. The question is : How do i get the blade to seat snugly with no wobble?
I figure maybe a strip of leather around the throat might do it.
Any tips, hints, comments are welcome

George: I sincerely hope you are doing your sheaths with the permission of Bud Nealy-he has a patent on the use of rare earth magnets used in sheaths, and, as far as I know, he has given permission to use magnets in sheaths to me alone.

Huh??? Is Gigand violating a patent?

If so I suppose I'll have to stop recommending their Mosquito. I just recommended it again this morning, too.

Had no idea that I have been violating a patent. Until I find out more about it I will have to stop offering magnets in the USA market.

At this point I would suggest that all individuals using ot contemplating use of magnets in sheaths in the USA cease and desist until Bud Nealy provides more information on his patent. It is possible that the patent covers only some aspects of magnet use but it may be more comprehensive than that.

Seems like pretty much everything is patented, eh? IF I wanted to make a sheath for personal use with magnets, though, just how much trouble could I possibly get in? Patents pretty much, at least in practice, only apply to people who are selling their wares, no?
 
I was stationed in Germany, twice, for a total of 8 years and I saw two sheaths that had magnets in them. One was a pukka type and the other was for a hunting knife. I thought it was a good idea then and to tell you the truth I forgot about it until I read the messages and the patent postings.
 
Is there any way to get in touch with Bud Nealy and find out what the story is?

I'm inclined to doubt the whole concept of using magnets in a sheath could be patented (the obvious to one "skilled in the art" clause, if not prior use) so I guess it's more likely to be a particular way of making the sheath, but who knows ... I guess if we can't get in touch with Bud Nealy we'll have to go to the patent office ... I think all recent patents are on a website now, aren't they? I'll do some searching when I get some time free and get back to you if I find anything.

O.K....Magnets aside...What other methods are used to keep a knife securely in a wooden sheath? How did the Japanese do it years ago?
Thanks for your input guys!
 
I called Bud Nealy this afternoon about the magnets. He said that the patent is on the sheath without the magnets. The magnets were an after thought and not covered by the patent so we are free to use them as we see fit.

For Tom rare earth magnets are magnets with some nomidium? and a few other "idiums added.
These increase the magnetic field density dramatically. Two 1/2" magnets are a struggle to get apart as each will lift about 7 pounds of steel. The 1" variety are good for about 30 pounds. I buy them from a woodworking supply company in Toronto called Lee Valley Tools, they have a web site but I can't find the information just now.

I usually bury 2 of the 1/2" variety in the top lip of my Bowie sheaths in case the snap comes undone. These guarantee that the knife will not simply fall out.

Bud thanks us all for the concern about the integrety of his patent.

Thanks for the info George. Now can I bother you one more time? Could you post the address for Lee Valley Tools on the forum and do they have a web site? Thanks
Tom

Hi guys,
Here is a site that has magnets for sale.
They seem pretty cheap. These things are strong. I haven't done business with them yet so i can't post a positive or negative feedback for them. An interesting site at least.
Also ebay.com has some on their auction site. Just do a search on "rare earth magnets"

To answer your original question shappa, using leather around the throat will help. But, it isn't necessary.

I have built a few wood sheaths and it isn't difficult to fit the opening so that the knife fits snug. Your idea about removing the wood in the shape of the blade and then gluing/pinning the two pieces of wood is just how you do it. Be sure and check the fit frequently while you are removing material. Pay special attention to the throat and don't remove too much material there. If you do it right the tightness and friction needed to remove the hard knife from the soft wood will be enough to keep the blade from wobbling.

I have been considering doing some wood sheaths on some small knives I am working on now. It is the tight fit and smoothness of removing/replacing the blade that makes them so appealling to me.
 
Thanks for the replies guys!
You've given me something to work with any way.
Thanks again Tom
