I had a couple of those back when I smoke, never actually used one except to experiment with with it., best I remember someone gifted them to me. Done my tamping with my thumb, bowl scraping with whatever small knife blade I was tote'n at the time, generally toted at least 1 Barlow back then, and pipe cleaner for the stem.
I inhaled everything I smoked, couldn't ever really understand the the addiction of people that just puffed on them, although some folks I knew were hooked worse than I was or at least had a harder time kicking the habit.
Sure glad I kicked the tobacco habit, soon to be 35 years ago.
