. . . my main question is this knife any good! because I have a chance to pick one of the newer knife-joy model up at this time,
I've never owned, carried or used the CTS-XHP (original) or the M390 (new) variation but I own many other Spydercos and all of them are "very good."
Using BHQ's blade steel comparison charts, CTS-XHP and M390 should be about the same in edge retention (9/9). toughness /6/6) and corrosion resistance (6/7) but CTS-XHP is considered easier to sharpen (5) than M390 (2). See:
Best Knife Steel Comparison.
If you believe these charts, there really is very little difference between the 2. However if, you're a M390 "fan" (like I am) you'd lean towards the the newer variation but, if ease of sharpening is more imporant, then you'd probably lean towards the original.
On the other hand, if you don't like "colored" Ti scales (at all or all that much) and don't like the way the color of the anno on the newer variation is said to "change" w/time and handling, then you'd probably want to go w/the original.
The size/contour of the blades/handles & wt of the knives is the same, so that's a push.
Based on my take on these factors, I prefer the original and would love to add one to my collection but I think that the original Slyze Bowie is grossly overpriced in the 2ndary market, which has nothing to do with whether I think the knife is "any good" or not.
I also think the newer variation is overpriced; just not as much as the original byou you're extremely unlikely to get if for anywhere near the release price of $400 but, if you can, GRAB IT QUICK!!!
If you have pay around $600 for a LNIB M390 variation (which is what they seem to be going for), are NOT a collector and actually plan to USE & CARRY the knife regularly, I think you'd do MUCH BETTER buying a Slysz Spydie Chef which can be had for about 3-5x's LESS than the cost of either the original or newer variation of the Slysz Bowie in the 2ndary market.
I am a "collector" and don't use any of the knives in my collection but I do own a SpydieChef and have no concerns about the possibility of NEVER owning a Slysz Bowie (based on current pricing). If/when the "market" in them "collapses," I'll be happy to buy one but, until then, I really don't care because it wouldn't even come lost to being the "best" folder in my collection if I was able to buy it for an acceptable price.
