Being rather new here, I find myself very very picky about what types of handles I want on my knives. My taste has changed dramatically since I first came round here.
First and foremost, any black color gets my immediate attention. If it's anything other than black, I might just scroll right past it unless I happen to notice it's in a pattern I like.
Second, I like smooth handles, so jigged and burnt are the lowest of the low on my "look at" list. I won't even consider stag...not on any level. Very much dislike stag.
Third, I'm not as traditional as some of you. I prefer materials like micarta and G10 and Delrin (not celluloid though, no way). I will look at some buffalo horn only because it's black.
Fourth, I prefer handles with minimal pins. If it's got more than 3, I'm not interested, regardless of pattern or material.
