When I began smoking pipes, I had just a Czech tool, which has a spade, no serraded knife. Now I've added added a another multi-tool, which has a blunt, serraded knife, and a flared sort of reamer (or do I have my wires crossed on the terminology?). I've looked for pipe-specific ashtrays online, saw nothing of aesthetic value, but I noticed that most of them have cork knockers. I'm wishing as usual that I had thought to ask this first, but I have been working to break in around eight new pipes (mostly briars, a couple of pears), and since I have put my Czech tool on my keyring, I reach for the tool with the knife when at home, being careful to remove the ash gently while removing the ash, scraping lightly if I see uneven, crumbly cake sticking to the sides. Got two briars and several cobs which aren't new which I've smoked on and off for a few years (now I smoke a few bowls per day, hence the growth of my collection), the briars seem to be in ok condition, and the cobs have a few black cells showing on the outside but still smoke ok, but I want to be sure I'm doing it right this time. Should I do no scraping at all, and use a cork knocker instead?
