help in Marlyand?

[neetones]

Hi everyone. i've looked up knife laws, but I really am having trouble making any sense of them whatsoever. Could someone give me a quick summary/answer this question?

I own a Beretta Airlight, and a Folding Crawford/Kasper as well as a Polkowski/Kasper Companion. Can I walk around with one of these in my pocket (or sheath in the case of the Companion)? Is it legal to simply carry one?

Also, would it be illegal if I was simply sitting outside whittling?

Thanks in advance.
