Aesthetically speaking, Black bolsters along with an attractive burl is my preferred Fiddleback configuration. Most of my collection is as such. With regards to my experience of the black linen micarta, I agree, it does "fade" fast and is likely not as durable as I would wish it to be in comparison to other materials such as G10, etc. For that reason, I tend to take a little more care and time in maintaining these knives. I love my Fiddlebacks, but if we're being honest, I do have dedicated, chef inspired knives for the majority of my food preparation. These knives are mostly stainless and made with composite handle materials suited for long term use in hot, wet, greasy conditions. Although it can be a pain, extra care goes into how I clean my Fiddlebacks after kitchen use. Lately, to help protect the steel and keep those black bolsters from fading (and to speed up my care process) I've kept a cotton cloth lightly saturated with mineral oil inside a ziplock back underneath the sink. After lightly washing and drying, I simply rub/polish the entire knife with the cloth and store it.
Although the patina is super cool, if I were to design my ideal Fiddleback kitchen knife, it would likely be a:
Woodsman with 1/8" CPM 154CM, high convex sabre grind, tapered tang, wearing stabilized black Palm, black G10 bolsters and black micarta pins. Pretty please wth a cherry on top!
BTW, how are you liking the Guacho otherwise?
