Think about it this way - manual action is like a manual transmission car, Speedsafe is like an automatic transmission car. You want to put a numer to how many people drive an automatic versus how many people drive a manual? I bet you'd find that the vast majority of the general public (like my wife) prefer an automatic transmission, while the car enthusiasts (like me) prefer a manual.
By nature, the enthusiasts are some of the loudest voices, but they are not the majority. The majority doesn't speak up very loud, but they do vote with their wallets. As a company we want to please both markets. You'll note that even though we make a lot of entry level Speedsafe knives, we also make 0777's, 0888's, 0600's, 0801's, 0560's, 0550's, and knives liked the Tilt, Volt, and Speedform. Every single one of those knives is a manual action. And wouldn't you know it, but every time we hear a few people say "it must be broken, I can't open it all the way". You can almost smell the clutch burning when they pull up with their new Ferrari. And that's ok - we're always happy to teach people to open a knife properly. But with Speedsafe they can do it every time, no instruction necessary.
At this point, we're trying out the compromise - offering some Speedsafe knives with a drilled detent hole. We'll see if it works. We generally try to do what makes sense for a particular pattern, and for the intended end user. Just keep in mind that Speedsafe continues to be very popular on a large scale. We are sincerely doing our best to offer a diverse product range and cater to both kinds of users - entry level and enthusiasts.
