You keep going back to that "Well, do you have a better idea?" thing. I don't think that really argues your point.

That said, I will admit, I have heard no one come up with a better solution than yours to that lateral stress problem that nobody feels exists. :thumbup:
 
Marcinek,
I don't think small folders(8" open or less) need to be pry bars. It makes

sense to laterally strengthen large folders though.

Yes, I understand you feel that makes sense. I think we all understand that that makes sense to you. :thumbup:

As a matter of fact, I do.

And being you've now asked this question twice, I guess I should respond.


As a mechanical engineer and an industrial design I have spent most of my working life re-designing chemical process plants, refineries and smelters to be more efficient, and more recently I have been involved with bridge work and restoration.

I do make knives as a hobby, but all have been fixed blades.

It was Bob Dozier that got me interested in the challenge of knife making.


Back to your question.

I have had talks with a major American knifemaker about making some high quality folders, but, unlike your obsessive design, we are talking about frame locks, liner locks, lock backs and slip-joints.

High quality knives built on proven designs are what most knife buyers seek, especial the type of educated knife users who frequent these forums.


Nobody get's rich quick in the knife business, but those that do their homework, pay their dues, play their cards right, and pay attention to their customers, might make a living doing something that is their passion.


Just one knife enthusiasts opinion. :eek:


Good luck in your endeavor.

Nice pic........but crowbars don't cut .......and small folders don't pry.

Why would a large folder pry?

If prying is so important for a knife to do then carry a 1/4" thick fixed blade.

Maybe I missed it but what are you imagining needs to be pried with a folding knife?

I mean if you have a fear of having to pry something and only have a folding knife to do so....then do not carry a folding knife and carry a thick fixed blade knife.

That way you will never be in the position of having to pry with a folding knife.


If you had a worry of having to dig a hole you would not design a heavy duty spoon for the task...you would keep a shovel around

:D:D Funny and correct all at the same time!!
 
LEGION 12,
Now if you could get that cutting crowbar to fold,......you'd be on to something !
 
Wow... This is just crazy how long this has gone on over 3 threads...

I was going to weigh in on the first thread urging others to give this guy a break and then thought better of it. Glad I did too because it got ridiculous fast. Now I just can't resist!

FFK- nobody that's into knives is ever going to argue against cool for the sake of cool. That's why many of us are into knives! Given that I'm prone to cut your idea some slack. If nothing else, it is "art for the sake of art" which I CAN appreciate. If you actually want to market/sell your knife to the masses though, you really need to refine its "purpose", the "problem" the knife solves and then actually PROVE why your solution is different/better. Others have said this, but it seems you're so focused on your idea you just don't want to hear it...

If you can't convince these guys who are "knife geeks" that appreciate "art knives" for the sake of "art knives", and "unique locks" for the sake of "unique locks" how do you expect to convince someone who isn't into knives to buy this product?

I'm intrigued by the idea, but you haven't made a compelling argument why anyone NEEDS this product? You think you have, but nobody is interested in viewing numbers or a CAD simulation. Instead of spending time doing more CAD simulations, its time to devote some time to testing and refining your message. If I NEED this knife- prove it to me. Take some competitors knives out into the woods and break them- then show me how yours WON'T break doing the same thing. THAT is how you sell knives/ideas.

There is the answer to the questions that you ask.

crowbars don't cut and folding knives don't pry


But crowbars to pry and knives do cut.

In addition, the liner locks, axis locks and Spyder back locks I use all open and close a heck of a lot faster and simpler than your creation.

I really don't understand this concept or knife at all, in the 20 years that I've been carrying and using knives I honestly can't remember ever prying anything with a knife fixed blade or folder. The reason for that would be I like my knives and rather not ruin them or injure myself by doing something as stupid as using them as a pry bar.
 
I saw something the other day that I wanted to post, but couldn't figure out where to post it. A guy from my church came over the other day to check out my new bee hive. I'm new to bee keeping, and he knows a lot more about them than I do. Anyway, the top frame, weighing maybe 30 lbs, was stuck to the bottom frame. The guy took out his case trapper, and pried the top frame free. It was inserted half way, and flexed far enough that I would have quit. But he kept going, separating the frames. The knife survived, with no apparent damage. I have never pried anything half so hard with any knife. I still wouldn't do that with one of mine, but I think many of us might be surprised how much a well made knife, even an old school case trapper, is capable of.
 
I am reminded of the cartoon titled, "Some people don't get the concept." A man is about to be hung from the gallows and with a big grin asks, "What's the best time so far?"
