Oh, CPK's are very much my taste...and I own eight currently, with a ninth already paid for future fulfillment. That said, I'm neither tempted, (at this point in time), to sell at the recent high prices...nor would I purchase at what I consider exorbitant prices. But that's just me.
I am fortunate that my interest in knives, and the hobby of amassing more than I need, does not have any deleterious effect upon my ability to put food on the table or meet our expenses. Were that the case, my answer might be different.
As to other knives, I won't suggest any in the CPK forum as alternatives, but I think you can get some great ideas in
this thread. There are some stunners there from many fine makers, custom and production.
