C10 Endura

The C10 Endura is one of Spyderco's most recognizable knives. It was first introduced in and won Blade Magazine "Overall Knife Of The Year" in 1990. The Endura was one of the first models that Spyderco made with a tip-up clip. It has gone trough 4 major revisions since its inception. It also debuted with its little brother the C11 Delica, they have gone through most major and minor revisions together.

Appearance in catalogs

Since at least 1993 the C10 Endura appeared in all Spyderco product catalogs .

These are the Spyderco Product Guides that feature the C10 Endura, that can be viewed online at the Spyderco.com website:

History, mentionings from the forums etc.

This information was posted by Sal Glesser on www.bladeforums.com:

The clip was modified (mold change) 6 times during the life of the plastic clip versions (1990 - 1997). All in an effort to keep the integral clip functional and strong. In the end, we changed back to steel clips.

Steel was Gin-1 (called G2 in the early days). There was a period when Gin-1 wasn't available from the foundry so we did a few runs with AUS-8.

Screw in metal clips were only used as replacements on these pieces when we had a break.

We went to the steel clip with the barrel bolt in '98.

We also worked with ATS-55 for a while which was a special steel alloy that Hitachi made for us. We were also testing VG-10 at the time from another foundry (Moran model). After several years, the market preferred VG-10 so we moved production to VG-10 on most models.

"Oddballs" can be common with Spyderco. We make changes as we invent/discover them so there is usually not a time schedule. If we learn that the smaller jimping, for example. is preferred on the spine, we'll shift the model based on production runs, not the calendar. Many of our dealers don't like it and it causes Joyce complications in the catalogs, but the customer (ELU) gets the most refined model sooner.

This same information can be found in a comment by Sal in the Endura date history question thread

In this post from 6 april 2021, Sal Glesser explains his experience on adding colors to both the Endura and the C11 Delica:

Our early knives were all stainless scales. We were chasing high performance low maintenance. In 1990 we added FRN and offered the Endura and Delica is several colors. Nobody wanted colors :confused: Black only. We ended up discontinuing the colors. It was a shame because I felt that colors changed the "sinister" attached to knives and said, "I'm carrying a cutting tool" and doesn't look like you are trying to hide something.

When we did add colors, it was dark, close to black but different.

Now we like colors :eek: So I would be interested in learning why you like colors on knives? :D And even what colors and why?^[2]

Here is so more info from Sal, posted on the Spyderco forums

The first Endura's and Delica's were made in 1990. We used a relatively thin integral clip as we had no history on FRN as a spring clip. When some of the clips broke, we added a thin strip on the underside of the clip for reinforcement. Then the 2nd version also showed evidence of not being strong enough, so we remade the tooling for the clip part of the mold and made the entire clip wider and thicker. This was done again a little later. We made 4 variations of the original integral clip before we gave up on the plastic clip and went to metal clips in 1998.

We began the model with Gingami I which was made by Hitachi. It was the best stainless available in Japan at the time. We couldn't put the name Gingami I on the blade becsuse the maker had used it for another company and wanted it to be exclusive for them. We went for a while with no steel markings on the blade. There was no US equivalent so when we decided to mark the blade, and we couldn't use Gingami I, we decided to make up a name and give the steel chemistry with the literature. We called the steel G-2 which stood for "Good Sh*t also". I tend to stretch humor a bit here and there.

As demand and production grew, we reached a point where the maker ran out of Gingami I and Hitachi didn't have any in stock. No one else was using the steel at the time so it was usually special ordered for us, but demand was greater than anticipated. The maker ordered AUS-10 as the closest steel available, but Aichi didn't stock AUS-10 and shipped AUS-8. A few hundred pieces were made with AUS-8 and marked G-2. Then we made the models for a while in AUS-8. We wanted to get it all sorted, so we got permission from the original company to use the name Gingami I (that was being saved). We chose to designate the steel as GIN-1 mostly to save space, but also to avoid confusion and keep everyone involved happy.

Then we changed to ATS-55 which was made by Hitachi as an alternative to ATS-34 (also made by Hitachi) and we were given an exclusive on that steel. We also were testing VG-10 by Takefu at the same time. Ultimately, we decided to use VG-10 for our main models and still do today.

I've always liked Gingami I as a good all around blade steel and we were importing the steel from Hitachi for use in our Golden factory. Then Carpenter made a "tweaked" version of Gingami I and called it CTS-BD1, which we are now using in our Golden plant.

Hope that helps.

Variations

Generation 1

The first generation was made with Zytel (registered and owned by DuPont) handles with a molded clip. Zytel is impervious to most enviroment and chemicals and is extremely strong considering its size and light weight making it perfect for pocket knives. Be that as it may the clip was prone to breaking off if it was bent too much so the next batches had thicker ones. (Spyderco is known for always refining its products and listening to their customers concerns). The steels used in these were either G2, GIN 1, or AUS8, sometimes the blade would not be marked with any type of steel at all, in that case it is the G2/GIN 1(one in the same)or AUS8. The handle came in three different colors black, green and red. (in future knives for Spyderco the color red has strictly been used for trainers only) There was also a black coated blade with black scales. The blade came in all 3 variations, full serrations, partial serrations and plain edge although all weren't made with every color handle. There are a few of these enduras with a metal clip screwed into the handle of a broken off clip-it endura. Spyderco would do this for a nominal fee.

Variations of the Endura 1

Generation 2

In 1997 the Endura 2 was released. It had AUS6 steel for the blade. Spyderco came out with a new model number C47 Endura II but later categorized it under the same number as the original endura, the C10.

Variations of the Endura 2

A note on steel handled Spyderco knives, many where embellished with logos of law enforcement & fire department agencies as well as spiderwebs with a Spyder on them in every edge type. Some of the variations that I have seen are F.B.I. , Sheriff's Dept. , U.S. Border patrol & U.S.N. Seal teams.

Generation 3

This generation of Endura was changed in 1998. Gone is the plastic clip, replaced with a metal clip that could be switched to either side of the handle. The barrel screw holding the clip could be tightened or removed with a few coins and it had a lanyard hole in the middle of it. The scales were changed to Volcano Grip for better traction. The steels available were either ATS-55 or VG10. As a funny sidenote it can be mentioned that the first C77 Spyderhawks had the Endura handle which said Endura in the little circle in the middle of the handle. (See picture in the C77- article).

Variations of the Endura 3

Black scales ATS55 or VG10 steel available in all 3 edge types

Black scales VG10 steel blackend blade in plain edge (this is the one i own, it might have been made with ATS55 steel and in the other 2 edge types)

Tan scales VG10 steel with partial serrations

Blue/Grey Emerson Opener (wave) VG10 steel in plain edge (500 pcs made)

Red scales (trainer) AUS6 steel

Generation 4

The latest version, the Endura 4 came out in 2006. It has some major modifications from the E3. First off are the scales, they are made using Bi-Directional Texturing (trademarked) which lives up to the name as it gives great tracion in any hand grip position that you hold the knife in. To further add traction jimping has been added to the spine of the blade. This is also the first Endura to have skeletonized liners (steel liners with holes cut in to save weight) to give it added strength without adding weight to the knife. The blade has a less pointy tip to avoid breakage. The Enduras have always been workhorses and because of that people have been known to push the knife to its limits and this change helps the tip remain intact. The clip is new and is connected to the liners with 3 small screws this allows it to connected in four different positions (tip-up/tip-down/left hand/right hand). The spydie hole has been enlarged to 13mm.

Variations of the Endura 4

Most collectible variation

Generation 1's in red or green, or black handled one with the black blade are getting harder to find as of late as well as any color with a combination edge blade. Endura 3 with the Emerson Wave opener were made for a self defense forum. It was limited to 500 pieces, of those a 25 were bought and embellished for Messerforum.net. (these are the rarest Enduras that I know of, although they are an aftermarket variation). Another somewhat rare endura (at least in the States) is the Endura 4 with Sal Glesser's signature etched on the blade . I believe there were 1000 knives made like this for a russian importer and distributor. The latest Sprint Run of the endura was E4 in bright pink limited to 600 pieces, many of which are still available. As mentioned above there are many steel handled enduras with logos of different agencies that are limited for initial sale only to thier respective members.
