From what I understand, trademarks must be vigorously defended. Moreso than patents.
The BladeForums.com 2024 Traditional Knife is available! Price is $250 ea (shipped within CONUS).

Functionality is presently both a cancellation ground for and a defense to charges of infringement of trademarks prior to incontestability.
Some products, because of popularity, novelty, extensive advertising, or other causes acquire secondary meaning not only for an identifying feature, but also for a useful or functional feature. If trademark law protected these features, the original producer would be able to establish a monopoly in useful goods. The functionality doctrine protects consumers from such monopolies by allowing competitors to copy functional features of a product, even if features have a secondary meaning.
Trade dress law is protected under U.S. trademark law if and to the extent that it functions as a trademark, that is to say it identifies the source of products or services and is non functional.

Seems the whole(pardon) basis of the trademark issued to Spyderco was the round hole used as opener. No trademark could/would be issued for a round hole anywhere on a knife used as a decorative element. Too many others have and do use holes as their signature marks on the blade and handle. Spyderco's unique claim is for the hole as an opening aid further defined and limited to round in shape. No prior use of any shape hole as opener can be claimed and excluding the round hole does not preclude or harm anyone else using a different shaped hole as an opening aid. The only harm would be to Spyderco in its hard won product identification with the round opening hole if its trademark was abridged simply by adding additional nonfunctional holes.
The only way I could see the "functional" arguement as applying would be if an additional hole was added to provide added function as in different handle grip(longer radius?) or left/right access or some other function other than opener. Maybe bottle opener?![]()
I think you may be missing out on the point of the functionality argument.

Jeep trademarked the shape of their automobile grill. I think that we would all argue that a automobile grill is funtional. Toyota created their own grill, their own identity, without attacking Jeep or trying to imitate their mark.
