I luv my Sharpmaker but, IMO, it really needs the CBN or Diamond rods to be truly versatile. Repair or reprofile work is difficult and time consuming without them and nearly impossible with any "super steel".
For a newbie, I would recommend the Lansky Diamond Turn Box TB-2D2C with 2 diamond and...
I use the Staedtler white hipolymer erasers for a quick cleanup of my ceramic rods.
But, for a thorough cleaning, I use Blue Scotchbrite pads and Dawn dishwashing soap on all my rods and stones, ceramic, diamond, whatever.
Used or not, most Camillus BK9's have some collector value, especially the sand-n-brown ones. Got the matching sheath, box, and papers? $$$
If *I* were going to mod a BK9, I'd sell the Camillus and get a newer Kabar with laser-etched logos. And then use some of the leftover Camillus-money to...
The Spyderco website just says it's "Out of Stock".
If an item has been discontinued, it will usually say "Discontinued" right below "Out of Stock".
They've never been 'cheap' in comparison and, with such a limited production run, they usually sell out immediately.
Check out the Spyderco...
FYI ... the Boker GoBag is available from US dealers.
I too have a couple of fixed blades in D2 and have no issues with it doing what I need.
As to cost, as already mentioned, it's not the steel that's 5x more but the knives. Comparing the Boker GoBag and Viper Berus 1, IMO 'yes', it is...
As I recall, Sal said that the CBN rods used a different process to bind the CBN particles to the rods which enabled them to hold longer than the Diamond rods.
I've been using the same CBN rods for a few years of light reprofiling of ZDP-189 and S110V without issue.
Lots of great recommendations so far, especially the ZT22 and William Henry B-5. :thumbsup:
But, since you've got a Spydy theme going with the PM2 and Manix, the Spyderco Lil' Native with Compression Lock in S30V or Rex45 would seem to be the logical progression.
Don't forget to ask the Krew on the Kabar subforum ...
I really like the looks of the 1266 and might consider getting one if I didn't already have the 8" Kabar Becker BK5.
