I'm posting and pinning this topic as much of the info discussed about blades, etc. is contained in this. This if from a former supplier of wood for ship models and he used the Byrne's Saw (aka the Jim Saw) for his products. Much of the info in here (such as blade tooth count, etc.) is also valid for other desktop hobby saws. He mentions in his text using Thurston blades but they quit the business and so this is recommendation for blades: https://www.malcosaw.com/ I
