I own both knives, so if you prefer theory and conjecture, move along, nothing to see here.
I have used both for field work, like skinning, as well as daily use.
Although you can take EITHER knife apart, the zaan is easier to disassemble and reassemble. However, Axis knives arent that hard to work on. It isnt rocket science.
Its a tradeoff.
The WilkinsRitter has a wider handle and is much more comfortable to use for extended periods. This is good for field use but isnt quite as nice for EDC. Again, tradeoffs.
Both blade designs work very well for field work and are among the best ever designed for this. However, some people, including myself, think CRKs heat treat is a bit on the soft side. This may or may not matter to you. The built in ramps and swedge on the zaan are great features though. They both are simply fantastic designs though and are excellent slicers.
Axis locks are still one of the best locking systems out there, extremely easy to open and close. I can open and close an Axis in half the time of a framelock. That being said, the zaan has the best framelock interface of any Ti-framelock made. If you want to get a framelock this is the one to buy.
Which one garners more admiration and attention from others? The WilkinsRitter.
Unless you hang around people who worship CRKs, the average Joes I run across always like the Wilkins better than the zaan. This may or may not matter to you.
BTW, someone mentiond a BM Mini-Rukus as an alternative to the WilkinsRitter. I have owned that knife too. It is NOT a good alternative. The handle and blade shape is not well designed for field use. Its a good knife, but for field use, it leaves a lot to be desired. I sold mine.
If you had picked any other knives to choose from, I could have offered a more direct opinion of my first choice. But these two knives are in my top 4 heavy use folders that I own, and I own quite a few. They are both so good.
Heres some specs you usually wont see, the rest you can look up :
Handle width: WR=.59 CRK= .47
Weight, ounces: WR= 5.45 CRK= 5.05
Folded length: WR= 4.5 CRK= 4.75
Hope this helps.
