All About Pocket Knives

hi does anyone have any cheap asst. openers for sale. my nephew is trying to start a collection. thank a lot.

Darryl,

I don't know what you mean by cheap, it's a relative term, but here's one I bought last week, and it's a sweet little knife. The first " modern " knife I've purchased, and now I'm afraid I have another whole catagory to be spending money on.

This would make a nice present to get a favorite nephew off to a good start.

If it's too expensive, maybe you could get your other brother Darryl to kick in.







Ok...........I'm sorry ! ......You're tired of that one.

Check the stores here at AAPK...should be some out there.

I am going to agree with them. Kershaw has a slick working asst. openers.

I just picked up a 1620 a bit smaller then the 1660 but it is less money.

Fits in the pocket and you don't fell it when your walking, but when you need a tool to cut. She will make you a very happy man...

Works slick to open your mail.

Just picked up a Jeep Leek kershaw 30 bucks sweet knife feel bad using my Case knives for daily users. This thing does the job of that and very well. I heard the 1660 Kershaw Leek got 2002 blade of the year.
As for that Pearl Inlay you got, sounds nice!

Just want to know if there is a big difference from Polished Stainless Steel Handle with Tungsten DLC Coating and Titanium oxide rainbow finish on handle and blade ?

The first one is on Kershaw 1615.
The 2nd one is on Kershaw 1660.

Thinfilm coatings, hmmn seems like it's right up my alley.

I'll start with titanium, its pretty simple. ALL Titanium has titanium oxide (Ti02) on it, naturally about 0.5 to 1.0 microns thick. Thats why you have to MIG and maybe TIG weld it. You can't glue, silver solder, or epoxy anything to titanium. Usually you will always see titanium handles are always held together with screws. Anyhow there are 2 ways to color Titanium. The first is the way your knife is done, just heat it by running a torch up and down and colors form and there are different colors for every temperature. Just run the torch up and down one side of the knife, one side will be hotter than the other and that creates the rainbow color or "heat annodizing".

To get a solid color you have to etch the existing titanium oxide (Ti02) off the Ti. Then the etched titanium is placed in an electolyte and voltage is applied. Lowest voltage creates a straw color, highest is green color around 130 volts. That's Titanium Annodizing, you have a stainless steel cathode in the electrolyte (TSP works well) and the anode is connect to the part to be annodized. If it's at 40 volts and no color is happening, the leads are reversed and your power supply may have blown a fuse.

DLC coatings are prepared in a vacuum chamber by plasma-activated chemical vapor deposition (PACVD) processes. DLC is called Diamond Like Coating. DLC is very hard and durable and it is only 1 to 3 microns thick, or 0.000001 to 0.000003 meters thick. Thinfilm hardness is not measured on a rockwell scale, but rather the Vickers Hardness Test - HV. In this case I think it is a metal-containing DLC film (MeC) and the tungsten was added to reduce brittleness of the DLC.

I think I'll stop there, I got tired of engineer talk . I used to repair and modify this million $$$ equipment and my memory of this is from 4 years ago. Like night and day.

That was a mouthful, but very helpful.

So I take it then DLC is called Diamond Like Coating. DLC is very hard and durable is better and would not show use marks as soon (scratches).

That was one thing I was so pleased with (hard to scratch) on the 1660 (titanium oxide (Ti02) on it), but it looks like the 1615 DLC Coating mite even be better.

You sure helped me and THANK YOU VERY MUCH for your time and brain power....

You're welcome! I only know it becuase I kinda lived it, lots of overtime - too much in fact. I worked a few 18 hour days and uncountable 65+ hour weeks. Your DLC knife is not pure DLC because of tungsten. so it is actually a metal-containing DLC film (MeC) and the tungsten was added to reduce brittleness of the DLC. So, it's Tungsten DLC or an MeC. They also use titanium, but tungsten is a very soft metal so tungsten should work better on a knife, adding titanium to knife would likely make the coating a bit brittle and may cause problems when sharpening.

Just think, they can grow man made diamonds to 3 carats about 5 years ago when I was reading an engineering journal. I wonder if they have grown it on a knife blade, if not in the future they could do it, but it may be cost prohibitive. They need a seed (or piece of diamond in this case) to grow the diamonds (at that time only yellow diamonds).
If they are able to grow diamonds with out seed, I guess they would use a PEVCD (Plasma Enhanced Vapor Chemical Deposition) process.

Sportsmansguide has 3 or 4 to choose from. A new Schrade, a Kershaw, and your choice of a Camillus Blaze or Heat.

I went to the annual Kershaw factory sale this weekend. I have a bunch of great stuff for my AAPK store as soon as I get it listed.

Here is an assisted opener I picked up this weekend; Kershaw Leek in carbon steel Damascus. This is a very sharp knife, even for a Kershaw. I have never bought a Kershaw second before, but I did buy 3 of these Damascus Leeks.

I had a chance to talk with the manager of the factory & he told me they only made 5000 in Damascus & they had a batch of blades that they sent out for grinding & they came back with the wrong grind. He said they were only supposed to be ground on one side, but they ground both. I guess they put the blades in frames & sold them as seconds.
I think I got a good deal. The firsts (which are long gone) sold for $129.95. I got the seconds for less than $50.

Another bonus of my conversation with Craig (the factory manager) was that he showed me how to tune the action on a Speed-Safe assisted opening knife. In his words, “There is a lot going on in there in a very small space.” The little lesson was worth the trip up there by itself! They are a nice bunch of folks at Kershaw.

A big bonus of Kershaw’s assisted opening knives is that all of them are made here in the USA, in Tualatin Oregon to be precise.
