I really like my S30V RSK-1. It is my first real knife after owning only SAKs and multitools for many years; and it started off my recent Benchmade collecting trend. But because it's my first real knife, and since I'm a noob, I can't give it a fair and thorough assessment--or compare it to other high quality folders.
I would like to mention that, in terms of balance, it is way blade heavy. The handle weighs close to nothing and all the heft is in the blade. Overall, the whole knife is really light, though. And if it rides clipped in my pocket, I tend to forget it's there--until I try and sit down.
When it's open and in my hand I think: garden tool. To me, there is nothing menacing or tactical about it. My sheeple, who've seen me with the RSK-1, initially cower from the width of the blade. The width does seem to make it look huge. But they quickly get over their fears when I introduce them to the axis-lock, and then they start viewing it as a fun toy after opening and closing it a few times on their own.
I was too timid to use my first RSK-1. I didn't want it to get scratched or dulled, so I bought another (used) one on eBay. I've carried the eBay RSK for a few weeks as my EDC and used it at work to open parcels, cut cardboard, scrape adhesive stickers, and eat lunch.
The only thing that bothers me about the RSK-1 is the sound it makes. It makes a plastic sounding click when flicked open. This is probably due to the use of half metal liners instead of full liners.
Less than 3 inches is considered legal carry here where I live. So I just had to order the mini-RSK. It arrived yesterday. So far my impressions of it versus the big RSK-1 are good. The plastic clicking noise is gone, probably because the mini actually has full metal liners. Also, the mini just feels more solid. If I tap the big RSK-1 scales with a fingernail at certain spots, I get a hollow shell feel. I don't get that with the mini, it just feels like a solid piece.
I'm eagerly awaiting news on the M2 versions. Last I've heard, the sales have been suspended. As soon as aeromedix puts the link back up, I'm going to pounce and order a large and mini in M2. And Ill probably end up not using either of them for fear of scratching their virgin coatings.
