This is Ralphs OTF 1 double action Out the Front interframe auto. The knife measures 9 5/8" open, 5 1/2" closed, and has a 4 1/8" satin finished stainless steel blade. The stainless frame is fully engraved by Dewey, as is the slide. The interframe inlay is pre-ban elephant ivory. The OTF 1 model features the front release slide. Dewey makes very few of these, and they are very hard to find.
