I purchased and printed Flint's Axe and Knight's Sword at the same time and I have to say unless you're a huge fan of the dwarves of Krynn give this one a pass, Knight's Sword is objectively a much better adventure.
Again this is one of the better scans of the old TSR product and looks great.
If you want more information on Flint Fireforge's family there's some really good content to be had in here.
Other than using Flint Fireforge's name repeatedly and having a Minotaur Wizard as one of the NPCs nothing about this adventure feels native to the world of Krynn. The adventure is a largely generic fetch-quest happening in a small, generic underground setting. The Tyin (the creature on the cover) is effectively the big-bad of the adventure and once again does not feel connected to Dragonlance/Krynn in any way, in fact the monster looks and feels more like something that belongs in a Gamma World game.
Overall if you want a short dungeon crawl or further information on Flint Fireforge this is descent value for the money but if you wanted something that feels more thematically linked to the world of the Dragonlance novels I would give this one a pass.
