These pictures are all reposts from other threads, but here's another look. All the knives shown below were made by H. Boker & Co's Improved Cutlery (Circa. 1869-1914).
MRB: That is the only H. Boker office knife I have ever seen in pearl (except in old pictures). If you ever want to sell it, please feel free to keep me in mind

. GREAT knife & GREAT thread! I hope there's a lot of old knives posted.
Ricky: NICE knives!! This thread's got your name written all over it!
Below is a link to more pictures of old H. Boker knives if anyone is interested:

A pocket knife is still an intimate personal possession of the individual who carries it and consequently deserves the best of materials, finish and workmanship in its production. (Quoted from Boker's 1928 cutlery catalog).
