First, welcome to our forum. I wanted to jump in to clarify something in the interest of being transparent. With regards to purchasing through Amazon; yes, Amazon is an authorized Spyderco dealer, but we cannot guarantee authenticity due to their policy of co-mingling inventory with third party marketplace vendors. Even something purchased "from Amazon" and "shipped by Amazon." This applies to any product, not just ours. Since they co-mingle inventory with third party vendors when an order is pulled and shipped we can't guarantee that what you are receiving is from inventory shipped by us to Amazon. Amazon does have a strong return policy though so if you ever receive anything suspect - again any product, not just ours - be sure to get in contact with Amazon regarding your concerns.
Specific to what you've posted: we would recommend that you send those knives into our W&R department for review. Ultimately, that is the only way we can definitively say if they are authentic or counterfeit. You can find all of the info you need here, https://www.spyderco.com/edge-u-cation/ ... hp?item=24
. In all likelihood, you've got two genuine Para 2s, but we can't guarantee that without seeing the knives in person.
Thanks for posting and we hope you enjoy your time with us.
Make it a good day!
