Welcome to this subforum!
Where can I buy a CPK knife?
Information is posted here-https://www.bladeforums.com/threads/the-next-sale.1405869/ and sometimes a few models are available at https://carothersknives.com/shop/
The sales take different forms but it is usually a Friday Sale at 1500 EST- you can order one knife per post. Get used to seeing all the knives disappear in a second if it is a new release.
But do not fret, Nathan usually has multiple sales or a pre-order of a new model till the market is saturated (at least in the short term).
Knives are also available in the secondary market at https://www.bladeforums.com/forums/carothers-performance-knives-for-sale.967/ -recommend choosing the "Watch Thread" option so if anyone posts a knife for sale, you get an alert. If you see what you like, you have to be quick to respond, as usually the knives don't stay unsold for long.
No chit chat in this thread please.
Knives also do popup from time to time, over in this sub-forum: https://www.bladeforums.com/forums/for-sale-fixed-blades-individual.891/

Important update: Folks, unfortunately scams are getting more sophisticated. Please make sure that 2 factor authentication or passkey is turned on, and if you are buying something on the exchange and something seems off, ask for more photos...(for example, ask the seller to add a handwritten note, a particular code, or photo of the knife from a specific angle...in addition to already required details), or ask for help from the moderators if something appears fraudulent.
From Nathan Carothers:
I want to warn people, there are scammers on the internet now, so you need to beware.
We don't send PayPal invoices anymore. Our Swipe (SwipeSimple) invoice will come from AIM Industrial. If it's somebody else, it's not us.
