Hello,
I am curious about what is the original portopee (dagger knot) for SS DAGGERS and SA DAGGERS . What is its specifications should be.?

SA Daggers never had portepee's Chained SS just an army type portepee to show officer in the waffen SS after 1942.

Do you know SS dagger portopee 's specifications? color ,how long should it be.. etc?

As indicated, the portepee worn on the chained SS dagger was a 42cm silver/grey army portepee. Hope this helps. ~ Ian
