Zookie, welcome.
I'm just kidding about being such a tactical badass. I seldom actually wear that gas mask.
The 2 and 7 are an awesome combo. The 2 and the 9? Even better, but I'm partial.
As for mods, lots of folks strip 'em so they have to wipe down and/or oil their knives on a regular basis.

With the stock grivory scales, you can tape, stipple, cover, sand blast, you name it.
Some folks have ground their Beckers into "It used to be a Becker but now..." shapes.
Micarta scales are available for the knives for an extra cost. These are excellent scales made by Ka-Bar.
On the secondary market, however, there are all sorts of custom scales, from wood to G10 to glow-in-the-dark stuff.
I hope you get a Becker, try it out, and hang around for the fun. And the tactical badassness.
Ssssssshhhhhh. Don't blow my cover, or I'll infract your ass.
