I can't say that I've had any earth-shattering revelations really.
When I first got back into traditional cutlery, pretty much in line with when I joined the forums here, I was attracted to mid to large sized, single spear jacks. Over the course of my collecting, trying new things, and getting all the exposure I could, my tastes have certainly changed, or evolved, I suppose. I don't value a spear main in most cases anymore and I've certainly developed an affinity for styles that were not on my radar initially.
Three blades are too many, unless the third is a punch. Two blades are just right in most cases - with Clip main, coping secondary or Sheepfoot main, pen secondary being ideal combos. When it comes to single blades, the Lambsfoot reigns as king and, in my opinion, renders most other multi-blade options as null. I prefer longer, nimbler blade shapes than I used to, finding them more versatile than broader versions (e.g. turkish or California clips vs. regular or lambsfoot vs. sheepfoot).
When I had my Rhidian Lamb done, I didn't know what I was doing to myself. I paired a favorite frame with a favorite blade that was based on a vintage example and in doing so, I obtained the perfect knife. It's made the pursuit of pretty much anything else pale by comparison. It's delightful, yet melancholy at the same time.
As such, this represents what I carry on most days. I'll throw something different in the mix now and then but in my mind, I've achieved perfection with these two.
