Dude, IMHO, unless you really wanna put your wallet on the Slimfast diet plan from hell, you just got ahold of probably the BEST all around heavy duty knife, PERIOD. **AT THAT PRICE POINT**, and Id love to have a SYKO, if I didn't have to pay $100 for a sheath to carry it in.
Now, you could look up Himalayan Imports on this forum site, and Im sure Aunty Yangdu can come across w/ a khukuri from Hades at about $200-250, maybe alot less if you "shark" a "blem". The only knife I can think of that would give a CSGK a solid run for its money is the HIMIMP 18in CAK.
Damned thing is nigh-indestructible. I would LOVE to see a HIMIMP 18in. CAK go up against a CSGK in SK-5, or 01, in a "blow by blow" re-creation of the CS PROOF videos. Not to start a feud, its just the knifehog in me thats all

.
Barring all that, you really got some excellent "raw material" to customize, no matter what you do w/ it.
