Shhhhhhhhhhhhh, don't tell anyone now cause it'll let the "cat outa the bag"....
Most military knives are never used in the clandestine business of sneaking up behind some unsuspecting bad guy and slitting his poor old throat! Actually, a garotte works far better....keeps 'em from making noises...
I carried a model 18 Randall in Vietnam.....daily carry now mind you....of course, whilst sheathed, there's no worry about reflectivity...duhhhh
For most activities involving the need for a knife, I reached into my jungle fatigues and pulled out an old trapper-style QueenSteel pocketknife....
I've seen some Randalls that have been "blackened", blued or somehow coated with something to darken the blade.....nowadays, with the readily available powder coating,etc....the Randall owner has many options....
But given what I've said above, I doubt that most Randalls are used in such a fashion that being clandestine is an absolute necessity...and when such necessity arises, there are seemingly infinite fashions to disguise and quieten down the glare off a Randall blade.
Frankly, I'm turned off by this notion of "tactical" knives...some like 'em...I don't....I think it's a "boy racer" kind of mentality...
Not to say that certain "black ops" guys might not have need for some of these so-called "tactical" knives but in all candor, I think it's mostly a "romance", "billy bad ass", "wannabe" mentality that sells those evil black knives....
Remember too that knives are definitely not on the short list for the politically correct nowadays....and making them with serrations, talon curves, slits and slots and references to "blood grooves" and all that crap don't do much for the image of us knife nuts.....
Randalls on the other hand....even the models with sawteeth are so damned gorgeous that most folks don't cringe when they see them...that plus the fact that most of Randall's knives are designed for hunting , fishing, skinning....plus some kitchen knives...makes them mainstream....as opposed to such things as the masters of defense, busse, etc....
