All About Pocket Knives

i was wondering if anyone else had a case 6001 trifold,if so i would sure like to see a pic.thanks.,. please refere to my previous posts for pics,thanks again.,.

Here's an advertisement for a 361 trifold from 1993

What the heck was the reason for that one. Seems Case completely forgot the KISS principle.

the main reason being, when open and in use it COULD NOT close up on you and cut you, a very safe to use deisgn, much like the neft saftey knife. and as far as KISS whats more simple than a knife with no backspring to weaken or break or bolsters?

Got'cha. Thanks.

Does this one have green bone handles? They are very expensive,if handles are in good shape.

i have a case tri fold in great condition

I've never seen those before. I love those with the bone scales.

Plus, it had Blackie Collins name on it for extra advertising glitz.

this is a very rare knife the pick at the top is the second one i have ever seen . i was told they never went into production with the 6001 is that correct ?

the handles are green bone , this is in mint condition , hard to get conformation if this knife did or did not get into production , someone told me the handles are worth about 300. an inch ?

Sargent's 7th edition gives a value of $1,500 for a 6001 Tested XX with green bone handles.

what year did that come out ?

Sargent's 7th edition came out in 2008.

thanks for the info..
thinking about selling this knife so trying to figure out value and from what i can find this is a very rare knife by the amount of people that have ever seen one of these, i think the book value given is a good price and may even be a little more today.
thanks for all your help ,

Both those knives (the old ones) are quite nice.

I see this pattern rather frequently, but by KaBar, not Case.

I'd be interested in knowing how the pattern went from Case, with examples being quite rare, to KaBar, with examples just about everywhere, seemingly.

Marbles made fish knives like that with nickel silver handles, they still make a Chinese version. Never seen a Case before, thanks for posting it! That bone is very nice.

wow that sure is a beauty,never thought id see another one.mine was in a little better shape before going under salt water during hurricane katrina.i sent an email to case a couple years back.a fella from case called me very next morning told me he was 76yrs old had only laid eyes on one in his life.im proud of mine it belonged to my grandfather,Myron Barber(bernardston,ma.) b1898 d1985

I do have one of the case number 6001 trifold knives. The scales are the most beautiful things I've seen. I have a lot of books, but I have never seen it in them. I'm glad to see this information so I tell the kids not to give it away. Mine, I have not polished as that's the way I prefer collecting. Thanks for all the input fellows. JK.

I have one, as do several others here. Mine has beautiful Rogers Worm groove bone covers. Courtesy of the keyword search here are some more posts and pictures. search.php?keywords=6001&terms=all&auth ... mit=Search

Here are a few pictures of mine. (It’s not polished either). After some research I have concluded they were made for Case on contract by Union Cutlery/KA-BAR in the 1920s. Although the stamps say CASE BRADFORD and CASE’s TESTED XX, which on a Case pocket knife would indicate an earlier manufacturing date, the patent for this design belongs to KA-BAR and is from 1924. The stamps on it more likely conform to dates used on Case’s hunting knives. JMO. The CASE 6001 is seldom seen, however there are a lot of KA-BAR examples around, having synthetic black or yellow covers.

I think all the Case marked ones were made for them by Union Cut.

Beautiful knife, Ken. I really like that old Rogers bone.

Thanks! Makes you wonder why someone hasn’t duplicated it, or pried the old tooling out of mothballs. Sure would make some beautiful knives!
