Yes, I agree. In fact, I was rather leaning the other way - towards 1/8“ - for a blade approaching (or exceeding) 4“. Having said that, the difference is even smaller than what you stated - only 1/32nd of an inch...
A Trailhand is very high on my list and I have been considering it. In addition to my new Warthog, I also have another similarly-sized knife in OD micarta (I do love OD micarta) so that I thought i‘d like to mix it up a little. Especially as I have seen the beautiful work Chris has done with wood. Your Trailhand, for example, is a favorite that I have admired in many a picture. Just waiting for the right one. Taking a gamble here and waiting to see what this week‘s batch will reveal.
ETA: Another 2 or 3 or ... OKTs are definitely in my future. The Warthog was merely the first. Since December I have taken receipt of 5 knives. I have volunteered that I live in NYC, but I didn’t say I was wealthy
. I need to rein it in a little...say, at least for a week
OKTs bring to mind the old saying “I can resist everything except temptation” (yes, there was a time I smoked Chesterfields).
