For some time I’ve had these drawings of a new series of user knives. With these knives I wanted to combine the properties of a slabtang and a sticktang knife. I finally was able to make a prototype which I will take to Schotland this week for testing.

My ideas:

The advantage of a slabtang knife is in my opinion that there is a lot of steel in the place where forces are generated when prying for example (near the indexfinger). A downside are the slabs, which in my opinion are never a real integral part of the knife.

The advantage of a sticktang (again in my opinion) is that the grip is completely locked by peening the end of the tang over the buttcap. Downside is that you have less steel at the ricasso/tang area (not a problem at all when properly executed, but I’m thinking pure theoretical).

My prototype combines all good properties from both types of knives. What I did is create a construction like you’ve probably seen in extrema ratio for example and combined it with the sticktang principle. So you still have the peened tang, enclosed grip and hardened pommel for hammering but also a lot of steel in the mid-section.

For the grip I used rubber (thanks Ed) since it is hard to beat when considering grip, warmth and shock absorption. Downside is that it can be compressed. If I would start hammering, the buttcap would start moving on the rubber, maybe even coming loose from the rubber despite the epoxy. To solve this I made a shoulder in the tang and placed a piece of micarta between the rubber and hardened buttcap. In the real version there will also be an extra pin in the buttcap.

I made this one stockremovel out of O1 and gave it a foliage green gunkote finish. The real ones will be forged out of O1. In the pictures the knife is just fitted but not yet assembled. I’m going to glue everyting together tonight, so cracks will disapear.

This is the smallest version, there are also three bigger ones.

ok here are the pics, I’m curious what you guys think:

That looks great :thumbup:

Im a big fan of ER, I very much like your take on their style of handles.
 
As I already said on other fora: nice design. Make a damascus one with a nice wood handle, and I'll be all over it!

Kind regards,

Jos
 
"Make a damascus one with a nice wood handle, and I'll be all over it!"

Could you make one like that? It would be really nice. This one is nice too.

I like the design, the materials, and the concept. Congrats on a nicely innovative design. How is the buttplate attached to the tang? Glue only?
 
Any idea what the price range would be?

Since this is the first prototype I have not yet decided on the price. But it will be between 250 and 400 euro's depending on the size of the knife, including a handmade kydex sheath system.
The sheath system is on paper only, have to make it still. Will be something you can carry in many different positions and places (molle webbing, belt etc.)

As I already said on other fora: nice design. Make a damascus one with a nice wood handle, and I'll be all over it!?

Jos, I think this model will be very nice in damascus and desert ironwood, some new silver and damascus fittings. Will certainly make one like that in 2009.

No the tang will be peened over the buttcap and glued. double safety.

Allright! Can't wait!:thumbup:

@dejo: welcome on bladeforums!

Kind regards,

Just back from Scotland, was a nice and wet experience…
Apparently it had rained for the past 2 months and made everything just a bit more wet than usual. Perfect conditions for testing a carbon steel blade.

Together with a few friends we hiked through the Scottish landscape and camped there (pretty basic.)

I was curious about doing fine work with the knife and to see how it handled in wet conditions. I can tell the knife has been wet the whole week and that the gunkote gives excellent protection against rust. Just the edge got some black spots, but after cutting a few things it shinned again. The peened end of the tang I gave a cold blue finish (not enough time to properly coat it). It started rusting the first day, so it has to be coated.

The rubber grip turned out to be great at cutting wood, berries, roots in the firepitt, and chopping branches in these wet conditions. Even when mud came into the mix, the grip was still very positive. Point of improvement is the guard, I’m going to make it a few millimetres longer for a more protection.

All in all I’m very pleased with this design. I’m now starting some harder tests to get any weaknesses on the surface.

We flew to prestwick airport and went a 45 minute drive south to loch doon. From there we started walking. Really nice scenery, especially when you're from Holland were everything is flat....
