I cant really find anything more detailed than that at the moment. I live in Saginaw; I basically take the 3 inch blade excerpt as you can concealed carry a knife with a blade 3 inches or less, and anything with a longer blade I open carry(which is legal in Michigan for both Handguns and knives). That's generally my rule for fixed blades; I carry folders with blades longer than 3 inches such as the Spyderco Tenacious and Resilience, and even if you ever get stopped or questioned by police they would have to prove intent. Any other insight from anybody would also be appreciated I try to keep up on this stuff but I often don't have the time. Hope this helps somewhat
