Ingredients:
One Canadian Mold/Tool Designer armed wtih state of the art Solid Modeling Software.
One Texas Knifemaker with nothing to lose and a lot to gain.
Some imagination and inovation with capital I's
A hank of free time......viola! You've got yourself the beginnings of a Hurricane.
A fun and challenging project for sure.
Rob and I would like some feedback, questions and interaction as we break what we hope is some new ground in knifemaking.
Thanks for stopping by. Rob Lemmon and larryd

Hey Larry,
I love the handle,,it looks great.:eek: I'd prefer the blade to have a little less going on. A deeper belly recurve, perhaps. I like the thumbdisk but prefer it to be metal. Maybe an oal of about 71/4"-71/2"?

Larry, I think the overall handle shape is great. I love the flipper style integrated into the guard. If you can pull off that clip, you're a hero! :)

I'm with Phil on the busy blade shape. Less pizzazz and more beef... I *do* like the kewl swedge and how it fits the handle.

I love the contrast of materials on the opening disc. But, maybe not plastic or composition. Somehow that reminds me too much of a cheapo Chinese knife.

Overall I give it a BIG thumbs up! You guys done great.

I like it. The blade is a little busy but unique. I would suggest that the disk be replaced with a set of studs that are used as blade stops. This knife just begs to be flipped open.
 
What kamkazmoto said. Integrate a nice set of studs in there and you've got a winner in my book. The blade is pretty wild, but I still like it. It's got a good flow along with the handle, and it looks pretty good closed.
 
I like the flipper so much I dont see why it has a thumb disc. Love the curved fuller in the blade. Dont like the plastic handle look.. Carbon fiber would be good but may not be practical for mass production. Dont use plastic ever. Will that pocket clip work or break off? The blade shape doesnt seem to be a match with the handle shape. Love the handle shape though. Love the double guard style bolsters.
 
These are the specs and write up Rob did for the Design Constest: ld

Here is the submission I made for the design awards as well as a technical drawing to give you an idea of the specs:

This project is about to begin it's prototyping phase.

Write-up:

Renowned custom knifemaker Larry Davidson has collaborated with Korver Engineering on the design of this Police/Military Folding Knife. While designed to suit police and military tactics, the materials, finishes and limited production run will market the blades towards an elite group of collectors and enthusiasts. While most "collector" knives are laboriously handmade, the components of this knife will be made using technologically advanced design and production techniques. The components will be fitted together by hand to ensure flawless function and a true "custom" feel.

This knife was designed completely in SolidWorks 2003 using a variety of modeling techniques. Multiple surfacing techniques were used to generate the blade, ergonomic handle and contoured pocket clip. Multiple configurations as well as assembly mate manipulation allowed simulation of the blade pivot to assure proper function. Mass properties were analysed and features were added to reduce weight and correct the balance point of the knife in its open position. Sheetmetal features were used to design and simulate the function of the integral leaf spring blade lock. The convergence of technologies in SolidWorks brings new design, analysis and simulation tools to a time honoured craft

Wow! Thanks for all of the feeback! I love getting an emotional response to my designs. A few points:

1) This will be a limited production done by Larry in his own unique style. It is not intended for mass production.

2) Per the above, no moulded plastics have been specified for any of the components in this folder. Final material choices have not been specified but I think either Carbon Fiber and G-10 would work well.

3) I designed the saddle type thumb bob based on a discussion I had with larry. I love the flipper ('specially with the Chew Voodoo bearing) but I realize that some people don't like it. Since one doesn't necessary hamper the function of the other, why not have both?

>>Edited to add: You can see a pretty beefy blade stop integrated into the top guard area. This flipper is definitely made to be flipped!<<

I love getting the comments, and we've started discussing some of the changes so keep 'em comin'.
 
Lazza and Rob,

Love everything except for the blade geometry. If I wanted an art knife, the blade would be perfect. For one to use (the only kind I have), a more "traditional"blade style would be preferred. Nothing at all wrong with the Davidson blades we see now.
 
can't get the dang pic up this morn, maybe to early??? Will try again. paul
 
I for one love the blade shape. Perhaps there is a slight mismatch between the aggressive blade styling (thats what I would call it...) and the more spartan handle design. I am thinking that a similar sort of fuller milled down the centre of the handle or even a series of fullers that would avoid the screw placements would tie in the appearance better and add grip.

Yes, the thumb disc is odd looking. I would keep the shape but maybe metal or even anodised titanium.

Having said all that, there is no mistaking the precise and amazing workmanship in that piece. Congrats, and good luck. Jason.
 
One of the things we were hoping to avoid was the over-complication of the design. There is enough going on in the blade that we decided to give a light touch on the handle. We may still consider adding engraved embellishments to the handle but we'll wait until we see the prototype in real life rather than just a computer model. Thanks for all the input guys!
