Two months since you placed the original order for the custom mini grip? Doesn't seem out of line to me. 2-3 Weeks until they made the first one, a few days till you got it, then you shipped it back? Assuming right the next day ideally. Let's say two days, you're already close to a month then. 2-3 days for them to get it, another day or two to process. Then they make a new blade, let's say another week for that, you're in the at about 5-6 weeks just for that, so you should get it back soon. Although it shouldn't take too much longer imho for a blade swap.
