$215 for G10 and essentially 440C? And list price was how much?! That's nuts, man.

DrMuttonchopsXHP is more similar to D2.

curly_haired_boy"Carpenter CTS™ XHP alloy is powder metallurgy, air-hardening, high carbon, high chromium, corrosion-resistant alloy. It can be considered either a high hardness 440C stainless steel or a corrosion-resistant D2 tool steel. " I know it's not the same as either of them, but those are both relatively basic steels. I like the CPM and martenistic stels I have, but that seems like a hell of a lot of money for a small benefit over 440C and D2. But, as I personally haven't used it, I can't say one way or another. :) I don't want to start a flame war or anything, it's just my thoughts. Have a good day man.
DrMuttonchopsI would agree in saying that the knife is expensive, but this is more of a collector's item. You could buy a functional knife for a fraction of the cost from Cold Steel if you want the same metal and performance.
But: CTS-XHP is similar to 440C, or similar to D2, in a sense that they are both steels. I understand that you got your information from a somewhat credible site but the author would not agree in the context of how you are using it. The three steels are nothing alike. Small changes to their atomic makeup can produce drastically different results. Essentially what was being said is that CTS-XHP is a fine grain, hard apex, corrosive resistant steel. Neither 440c or D2 are produced with powdered metallurgy, XHP is. 440C and D2 have relatively large production tolerances in their chemical makeup when compared to CTS-XHP.
CTS-XHP is a tried and true blade steel, holding it's own argumentatively above S30v: https://www.youtube.com/watch?v=W7D98zJE1bM I find it very dumb when steels are compared by their atomic makeup, which is not an attack against you but the knife industry in general.

Illinois_knife_guyFair enough on the collector's item part! I'm sure that it would still function well. I did get my quote right from the Carpenter site, though, which is why I was taken aback, since they made the comparison. :) I know that XHP isn't that new, which was another reason I was surprised at the price! Thanks for the vid, I'll give it a watch. And I didn't take it as a personal attack! Thanks man, have a great day.
DrMuttonchopsplease allow me to quote the chemical compositions for anyone interested:

Those small changes make way for large differences in an end product. Needless to say that [PM] powdered metallurgy (CTS-XHP) makes for an extremely accurate steel grain which is vital for edge retention. 440c and (most) D2 are ingot steels, which comes from an oven like a pizza.
ingot steel is like takeout pizza, just regular product that is what it is. [PM] steel is like ordering a pepperoni and sausage and the cook meticulously placed the meats in perfect alignment, so each bite is perfect.
I'm sure you knew this but to those that don't, now you do :)

Illinois_knife_guyThat is an amazing analogy. Thanks man!

Illinois_knife_guyAll of your information tell's a novice like me nothing. How does it stack up to S35VN or V10 or M390 steel? I've not a clue.🤔 It's an attractive knife, but what about the pivot and detent? I need more of your expert opinion before pulling the trigger on this one.
Jim74M390 is premium steel in a world of it's own. It's grain dense but very strong. (m390 is optimal when the edge is a wide angle, more than 23 ° ) This means m390 would not make a good kitchen knife where the edge angle is more acute than 18 °. source: http://www.zknives.com/knives/steels/steelgraph.php?nm=m390. M390/CPM-20CV is a very strong steel.
S35VN and CTS-XHP are similar to strengths. You will most likely not notice a difference except that XHP will polish better.
VG10 is a good steel but it doesn't compare to CTS-XHP.**
CTS-XHP has the capability of being a very hard steel. knowing Spyderco, they will get the heat treat right.
Your question about this knifes pivot need to be answered by somebody else. I wouldn't know. A quick search brought me to this video : https://www.youtube.com/watch?v=puAUwJir5C0
