Ken Onion Eros Gentleman's Knife
Ken Onion’s Eros Gentleman’s Folding Knives

Ken Onion is famous for the assisted opening knives he developed for Kershaw over a ten year period. Now that he has moved on from Kershaw to Columbia River, he also seems to have moved on from assisted openers. Not to worry, fans of fast opening knives, his new CRKT Eros folder opens just as fast-if not quicker. The secret to Ken’s new speedy folders is the bearings that the blade floats on-the official name is IKBS-that allow it to open like its on roller skates! CRKT is so proud of these knives that they are serial numbering them.
