Are Spyder Holes Liabilities?

The standard I use my knives harder then you do and I know lots of knifemakers argument.

You say your google search for "broken Spyderco" had different results than mine. Here is the screen shot of mine. The first two pictures are both Spyderhole failures...

I googled images of what face I should use to pick up dates. Two of them were these. So what?

I know many custom knifemakers, factory reps, and CEOs in the knife industry. I will occasionally open mouth, change feet, but I feel overall I have good rapport and mutual respect with them. I run a knife forum's facebook group with over 1,800 members in it, a prepper group, a military group, and two firearms groups with no problems.

Thanks for your time.

Cool story bro. Is that the final chapter?

As I stated earlier, both folders and fixed blades have thier purposes. EDCing a five to seven inch fixed blade is not always practical or legal as well as drawing unwanted attention in a lot of situations. A thicker quality blade with a titanium handle, pivot pin and screw would make a considerable difference.

This is my best answer so far. Combative Edge PX-41.

i dont like flippers, i dont find them as reliable as the spyderhole. ive had many failed deployments with flippers.
 
No need to stalk this guy publicly. His name is available to anyone who wants to research him further on their own. He's done his damage here. Admitted some mistakes and ignored some others. I like to deal with facts or opinions backed up with experience. What he looks like is of no interest to me.

His knife does look good. Sort of like a Kizer which name escapes me (it was mentioned earlier) or the Eraser designed by liong Mah and of course his customs. Still not appropriate to promote it without the correct membership level.

. I do have to wonder what some people do in the real world that cutting is the only thing they've ever used a knife for. Ever shelled and eaten oysters?

I dislike oysters. But I have shown you a Military taking down an Oak sapling and batoned into the stump.

Also that same Military has been used repeatedly to cut re-enforced hydraulic lines, conveyor belt, pry rubber collars of piston shafts, banding, industrial zip ties, shrink rap, etc.... And pry stones out of my boots. All while being soaked in hydraulic fluid and covered in stone dust and being exposed to sub freezing temps, rain, sleet, and snow.

This is what I do for a living.

What has your PX-41 done?

From my viewpoint, not having been active on here for sometime, it appears to be a boy's club and a bit of a cesspool. Lots of trolls adding fuel to the fire and jumping on the bandwagon. ....

Complete and utter nonsense. If you run those groups you know full well about a groups rules about self-promotion, the people who try to weasel around those rules, and the reaction those people get.

Yes, it weakens the blade. That's a fact. But, does it matter? There is something called engineering. It's where smart people use applied physics and math to design objects, test them, and then produce them according to a specific set of instructions. Spyderco knives don't fail under normal use. I've only seen a few broken ones in years on the forum. If they aren't breaking often then there isn't a problem.

If you need a very strong knife for prying then buy a pry bar.

Why are you being so condescending? OP had a legitimate question. Also, engineering and applied physics are two different fields.

Yes, it matters that it weakens the blade.
There is no possible way for any manufacture to foresee the extent "normal" use. There's an acceptable failure rate, not from abuse, with any product that the company accepts rather than spending more on R&D.

Also, look at how much companies celebrate their knives' locking strength. There's a certain point that something is going to give.

Nope; it's a red herring he's tried to use to push his own product with.

Dis-honorable behaviour like that is in no way legitimate. If he'll skirt the rules to sell his stuff what else will he lie about? Perhaps the very quality of what he's shilling?
 
My secret plan is lain: :eek:

Step 1: Get a bunch of Spydercos, clamp the blade into a vice about hole-deep, whack them with a hammer, and load up the internet with photos!

Step 2: Design a folding fixed-blade knife that is a folder that has fixed blade capability for when you need the strength of a fixed blade but it has to fold.

Step 3: Profit.

Foolproof! :D :devilish::triumphant:

about testing factory knives to the point of failure. He said Spydercos did horrible due to the Spyder Holes taking a big chunk out of the blade right by the spine and weakening them. I think the Spyder Hole was pretty revolutionary when first used, but would seem obsolete when we have flippers (Thanks, Kit Carson, RIP) and thumbstuds

Yes the hole weakens the blade at that point. Testing to destruction would show this, and you could of course concoct a test that would aggravate this. Apparently this doesn't matter much in real world use. Spyderco does a lot of product testing and I've seen videos of people beating on various Spyderco knives with no problems, and I haven't seen a report on these forums of a blade breaking through the hole. I suppose if a person really wanted a folder with strong prying ability they could pick a knife with a thick blade with no holes. I've also seen blades broken through the pivot hole so you might pick a blade that appears stronger than a Spyderco on the outside but it might break through the pivot and not gain you anything.

My EDC rotation includes many Spyderco knives but a few from other brands. I don't disassemble cars with my knives and have not had any problems with any of the knives. If I was concerned about a survival situation I would carry a fixed blade. One of the things I like the best about Spyderco is the hole. It works better for opening the blade than any of my knives with thumb studs or flippers.
 
Forgot to mention - warranty on this thread. The one or two instances where someone had a Spyderco blade snap (Im not even sure if it was through the hole) and posted it here on the forums eventually had their knives replaced under warranty. If this was more than a rare aberration (other reasons for blades snapping include heat treat,brittle steel types) Spyderco would have gone under due to the cost of having a faulty product. Point being, while a guy who breaks knives on purpose like Ken Onion couldnt get his blades replaced under warranty, the rest of us can if the need arises.

Another thing... PRYING seems to be a key word thrown around in this thread. Is anyone really saying that blades that DOESNT have a hole cannot snap from prying? Really? :rolleyes: Try again. Snapping due to prying can happen to any knife, dont insult our intelligence.

You 'bout done with that FFK yet? I need more strength!

If the Spyderhole is a weakness why wouldn't that huge choil be a weakness as well?
Click to expand...

Yup... It is actually its a bigger weakness than a hole with the same minimum radius, given a blade with the same minimum sectional area of the blade.

If one is going to pick on a silly point to try and shill a design its best to make sure the design isn't even more flawed... LOL...

I have post graduate education (Masters courses in Mechanical Engineering from one of Canada's most prestigious universities) on this subject (fracture mechanics), if you choose to question my expertise, then feel free to take four years of Mechanical Engineering and then we can discuss the post grad material in depth. :)
