LOL....Priceless!
What the OP was pitching for in my view is whether you ever eclipse the ability for your knife because of limitations in the knife....and for me that is a good question and is true.
You can become more proficient than a knife can deliver...some of this is easily said if you have a knife with inherant limitations....carrying only a SAK may well mean you cannot do certain things as well...this side of the arguement basically shows that there are "tools for each task" ....but... sometimes to have versatility you need a compromise knife which is going to be with you when you need it and can enable you to muddle through on most things.
Sometimes you are limited by issue kit...especially in the Infantry...SLR bayonets in the Falklands had little or no easily found general use ability. I remember seeing the Gurkha's use their Khukri's and soon picked one up.
The skill set I learned with that Khukri was way ahead of what you could do with an SLR bayonet.
Now with the proliferation of good designs and knives suited to some serious use I doubt it is easy to say "I have eclipsed my knife's ability to let me use my skill's"...a knowlegeable guy with a Wooden handled Mora, a SAK and a good machete like the Collins one ,would probably do as well as can be done ......even on a very cheap budget.
Our more expensive knives have good competition in cheaper tools if they are selected carefully. It was'nt always as well known though as to what was good on the bargain level. A lot of other choices were bad at that price range...but now there is a fair bit of knowledge out there...and who can say they are better than a Mora can deliver if it has the right handle on it?
