Superb knife buddy 👌 I have a big knife collection too, mostly vintage German hand made Puma knifes like the White hunter, jagd nicker, hunters pal, four star's etc. They have also the rockwell test. Great knifes mostly with stag handles. I never had a Rockstad i my hands, but if i hear the "klick"and see the knife i know exactly what you have there😁 As EDC i use a Böker Optima stag. This is also a great quality knife where you can switch blades in a second for every situation. Thanks for showing mate 👍
