World premier of my new HRD system:toxdance: The Hoback Roller detent gives significantly less drag on the blade compared to a standard detent. This is exclusive to Jake Hoback knives.

Now that Im done with the marketing gimmik side of things:haha:

Yall probebly know how this works but here it is anyway.
A normal detent in a folder is a pressed in ball bearing either .062 or .092 wide. it drags along the blade and keeps the blade in the closed position and lifts the lock off of the surface of the blade to keep the friction down.

The HRD system uses a rolling ball bearing to do all that a standard detent does, but with substantially less drag. A great side affect to this is that there is greatly reduced wear, and it is user replaceable.

I want to get this info out there and in the hands of people who can use it.
I am willing to give the information, sell the detents, or tell you where to get them made, to anyone that would like to use it. I only ask that I am given the credit for the device. Call it the HRD system, and use it freely. I hope that this can create a new line of folders that will be so smooth it will blow your mind.

I will be using this HRD on most if not all my folders from now on. I have been amazed at the lack of friction that I'm getting. I figured that if the pivot is riding on bearings, why not the detent too.

You will see a all titanium blade folder from me in the near future with this system on it:P no more plastic balls or ceramic that eats the blade

Look at the wear pattern on the detent area. cant even feel it with your fingernail. Thats 3 weeks of hard use from me. Ask anybody that knows me. I'm not easy on my prototypes!!! the chipped up M4 blade will attest to that.

That's pretty cool. I bet that sucker is smooth.

Any idea if this could be used in a set up where the lock bar has a removable steel interface?

Also, thumbs up for letting makers use this technology. That's very cool.
 
Thanks for the props:)

It could absolutly be used on a removable lock face.

Cool idea, Jake. Does it just sit in the hole? Also, how thick was the titanium stock before you carved it up so nicely? i REALLY like the fact that you have a proper handle scale on the lock side of a frame lock so no need for a "travel stop". By the way, that is one big honkin' stop pin! Looks like a second full sized pivot! :eek:
 
Do want!!!

I would love that folder in a left handed version with a bit of a darker etched stone wash finish on the blade!
 
does it affect the blade retention at all or can you just adjust for that?

I think implementing it as a plate shape or on a SS lock face would solve any potential hot spot issues on the index finger(just based off the knife showed)
 
Thanks for looking at my idea boys:)

I still need to sand down the head of the screw so that it doesn't protrude. It only sticks out about .015-.020 so I don't even notice it when in use, no hot spot to speak of. I am considering making it a flat tip instead of an Allen key so that would take care of grinding them to fit thinner frames.

The frame on that A15 is .220 thick, plus the HRD is setting right where I chamfer the edges of the frame. New models will get moved back a touch.


Bear with me for those who have asked for the info, I'm making a qword doc with the info on it since I got a lot of requests, but me computer crapped out on me and I'm switching over to a new one.

With any luck I can convince Thomas at Kershaw to use this system!:)

Adjustable detent sounds pretty epic.

Also, I really like that knife. That looks like a great EDC.
 
Just wanted to bring back the necro post:) as there are several makers out there using my system, wanted to see how yall like it and if you have had a chance to use it.

I have a handfull of my blades out there now with it with a batch of 50 coming out in about 6 weeks from me:)

plus a full write up in a mag soon!!! woot

if any one still wants the info, let me know!
 
Could someone that has some experience with the HDR system PM me? I would like to bounce some ideas off someone to see it if will work, I also am trying to figure out where to get these and what hole to drill for the ball?

Thanks for the help guys!
 
Interesting concept, thanks for sharing. I'm not very sure how it works though. Is there a tiny spring that presses the detent ball or is just the screw that holds the ball in place?
