Sergei Bobkov and Konstantin Pushkarev Collaboration

I haven't been able to find a lot of information on these two Russian artists, however, here is what I know.  Konstantin Pushkarev is a master of wood inlay work and has practiced his inlay work since 1996.  He has a firm  that is engaged in the design and creation of inlaid cutlery. Konstantin creates his own knives and works with others doing the embellishment as is the case with this knife from Sergei Bobkov.  I have not been able to find much information on Sergei.  I really like this knife and it would be great to find more collaborations by these artists.  I have not yet taken my own photographs of these knives, these are from Jim Cooper of Sharp by Coop.  By the way, if you want to see some great knife photography visit the Sharp by Coop website here; http://www.sharpbycoop.com/jalbum/index.html
