I honestly do not remember them being included that much. I say that as a fairly new subscriber who has been buying news stand copies or mooching reads from a cousin for years. To test a hunch I did a simple magazine index search on the word "grizzly" in their website. It came back with 17 hits that included about 14 issues. This goes back to 1995 and includes some smaller items like sanders, brad nailers, router bits, etc. This might not be an accurate way of determining actual appearances but it doesn't seem like much when compared to mainstream woodworking magazines.
Before anyone goes nuts, I do not consider FWW to be a mainstream magazine. It might have a fairly large following but the projects and skills shown fit a smaller sample of woodworkers than most of the mags. The magazine has an elitist tone that probably serves the skill level of writers and contributors; but perhaps not all of their readers. This is not a complaint because, in a way, it adds to the appeal of the book. I do find it a little curious that they chose to rerun a very early article regarding "woodbutchers". It might have seemed appropriate in their early days but it probably insulted some of their readers that do fit the mold of a mainstream woodworker. We are amatures, we know it and we are trying to improve our skills with FWW.
