I was just told a skeletonized tang has more strength. Is that true?

Yes the knife is still strong enough..but...my issue would be the maker/seller telling me something false regardless of the strength.

What is that expression..."don't pee in my ear and tell me its raining" :-)

A tube is "stronger" as in less likely to bend than a solid bar of the same material and diameter.
So in this particular case, removing metal does add "strength"; provided the tube is properly engineered for the application.

No sir, this is incorrect. At the same outside diameter, material and hardness, the tube will bend before the solid bar. The only way that statement would be correct and the tube would be stronger would be if the tube had equal MASS or cross-sectional area as the solid bar - in which case it would have to be significantly larger in diameter than the solid bar.

I stand corrected, and will delete my post.

Yes, holes and skeletonizing make things much weaker. And stress risers are very real. Believe it or don't, no skin off my nose.

So regarding stress risers does that mean circular holes are better than square ones? I think someone mentioned that before and it would make sense. The force would be distributed evenly around the circle versus directly on the corner in squarish skeletonization.

Not necessarily better, but the sharper the corner in a cutout, the easier it will be for a crack to start. Also the closer to the outside edge a hole is (whether round or not) the more prone it will be to cracking.

Yes. Sharp inside corners are bad.
 




:oops: Here's a pretty nice little knife I broke being stupid . Lateral pressure caused fracture at hole . Note damage to Micarta scale .

Yikes! Hey better to break it just messing around than in the field right =) I really want to do destruction tests on all my knives but I just can't afford it.
 
Ouch Doc. I'd say that illustrates my earlier point quite well. The pin and scale really did nothing to add strength there. When the steel gave way they went right with it. It doesn't look like the orientation of that pattern weld helped matters either, I'd say.
 
The problem is more where the holes are located. A simple pin hole for fastening the guard can be quite the stress riser : the transition from blade to handle is where the most stress occurs. Add a hole there and breakage becomes a possibility. And that's why some stick tang knives are way more resistant than some full tang knives : the stress is distributed evenly from the blade to the handle (no holes or sharp corners anywhere). The handle may get some damage, or the ferrule, but the knife as functional unit survives. Some full tang "strong as a beast" knives could very well simply break apart in the same situation if they have a misplaced hole.

Instead of breaking a bunch of knives for no reason, why not save up and just buy a few you know will survive almost anything?

Because I don't know what will survive almost anything and still be a size that is reasonable. A lot of people probably think the Bravo 1 will survive almost anything but after seeing that exposed tang it makes me question that assumption. Really the only way to find out is to test. That's why they do crash tests instead of saying well it's X brand it's good quality and will keep you safe.

Get a Swamprat, Busse or CPK and you will be fine.

It shouldn't be left up to you and I to do destructive testing for a knife manufacturer. They should do it themselves (or even better, sub-contract it to a reputable, independent third party) and then publish the results on their website and in their forum.
