I'm sorry, but as a collector as well as a maker, this is a bit of a soap-boxer for me... (Not that it should really matter. Just one man's opinion so please read it as such...)
Very subtle little accents are fine... But, when I see file work on the edge of every surface it leads me to believe the maker has some trouble getting dead flat surfaces to meet each other cleanly... It is a cool skill to learn, but I have yet to sell a knife that had file work on it...
There is a crowd that likes that overboard stuff. The thirteen different handle materials laid together with the three to four different types of metal adornments and then a whole ton of file work. So I am sure there is at least a market for it out there... Even the proportions on these particular Pakistani ones on the fleabay are way out of whack for me... but they do actually sell...
To me, it looks...
From a practical standpoint, file work is just a place for bacteria and other nastiness to accumulate. It is also a good place for a scale to start popping off, or to chip out if dropped. Sharp angles in file work are a great place for stress risers to start as well. I might add, when it does come to file work, some of my favorite that I consider tasteful is seeing file work with dyed epoxy laid into the file work to match a spacer. That looks clean... Like this...
I think it is one of those things that is faddish and kind of catches you up when you first start getting into higher end knives. You start looking at customs, and see the gaggle of them out there that have file work, and a first are really impressed. It looks cool, and catches your attention. Then you settle down and start looking at true fit and finish, or make a knife yourself and you realize there is more skill in perfectly mating two flat surfaces, or getting a clean 90 degree joint between materials than there is in marking off a spine and filing a pattern. The exception for me is when we are talking about folders. Folders are already, by nature, a hotbed for trapping every piece of pocket lint and crud from your hands. Just fitting up a custom folder is hard enough and shows enough skill that file work doesn't appear to be hiding anything. There, it looks good to go a little overboard. But, I have an exception in that I like the file work on the spring-back and liners, etc, but not on the blade in that case... Dunno, matter of taste I guess.. Like here, it looks good to me...
That's just my $.02, sorry if that offended anyone. It certainly isn't meant to. I have yet to see the OMG amount of file work that I see as gawdy from anyone here. Most of what I have seen here is tastefully done and in areas where it makes sense. And, it is another little thing that can be used to separate styles and continue to make room for all of us to have an audience with our craft... I have seen some very innovative and creative file work patterns out there, and those are pretty much an art form of their own. And that, I can certainly appreciate..
But, I'm not overly fond of mosaic pins either... Same thing: I can see the effort and talent involved, and the draw for those who do as they add another point of interest to a knife, but just don't particularly like them...
