This is folder (not 880 or 881), Strider collaboration, blade is marked "Strider Buck" and "SB.4" on the other side, handle is plastic, black plain blade.
What`s the model and blade`s material?
Thanks a lot to all.

Buck 889
420HC steel... I think

I think the SB.4 was the 889. It was the cheaper version of the Tarrani 882, I believe. I liked the plain blade it sported better than the 154 CM of the 882, but thats just IMO.
