Is the tsunehisa srs13 the successor to the akifusa (et al.) srs15? It looks fairly similar but difficult to tell because I can't find a great comparison angle. If the srs13 is the successor, is the srs15 line done for?
Also, anyone compared srs13 and srs15 in use? Zknives says that 13 is a newer version that contains slightly less carbon.
