This is an aftermarket customized Buck 110 Auto. It features nickel silver bolsters, rare green dymondwood handles and a dollar sign opening mechanism. The lockback works to keep the blade in the locked open position, although it doesn't take much to unlock it. The auto button keeps the blade in the closed position until pressed. This works very well, as does the automatic opening. We have included one of the new Buck sheaths made for the automatic version.
