I have a Pack Rat that I got about 8 years ago.
The overall quality of construction is superb. Handle ergonomics are also fantastic, although I think I would prefer a more abrasive surface on the G10.
The 01 takes and retains like crazy, and is very easy to sharpen. (Lack of) corrosion resistance would be the downside there, but that has not been a problem for me.
The big negative is blade thickness. Honestly, I bought the knife primarily because I wanted a representation of Kevin's work, and secondarily as a user. So I did choose a model that would be relatively useful to me, but that is of course not the same thing as choosing a knife entirely on the basis of its utility characteristics. 3/16" is just too thick for a knife of this size, IMO.
An 1/8", uncoated, convexed Pack Rat would really be something.
I've heard through the grapevine that Kevin plans to take another look at doing some new, small pattern knives. Don't know if that will happen or not, but sure could be interesting.
Yeah, AFAIK all the work is done by Kevin's hands, except sometimes cutting out the profile of the blank. The chroming was shopped out back in the day. I know he had some problems with that, but don't know if he brought it in house.
Like other makers, Kevin does custom work. There's always that bizarre debate over what's custom and what's not, with knives. In my mind "custom" means purpose-built to a specific design for a single end user. By that definition, a custom MD would be identifiable as not being part of the pattern catalog from the time it was produced.
Nice to see an MD thread sans political commentary.
