Smoking circa 2005 Gawith Hoggarth Dark Plug in an Estella 511 KS. Normally only break out this plug once a year on my bday (end of March), but a good friend surprised me over the weekend with a late bday gift. I had mentioned to him awhile back how difficult it was to cut these plugs, and he talked to his dad (an artisan knife maker) into making me a knife suitable to cutting plug tobacco. I was gifted this wonderful piece Friday night and wanted to test it on Dark Plug, one of the densest plugs out there! Was a fitting test for the new knife, and it passed with flying colors!
