I picked up a few knives out of a “knife box” in a shop the other day – most unremarkable. But I found this tiny (almost to the point of useless) Sheffield interesting – cannot find any info about it (or another one like it) online. Well-made, but nearly impossible to open one-handed). Another tactical folding knife had this logo on the blade – not sure if it is maker’s mark or not. No other markings at all. A very well-made knife and would love to know more about it. Does anyone recognize this logo? My research has turned up nothing.
