They did go from aus8a to 4034 for their micro recon 1. I think this is likely due to them switching to a different(cheaper?) manufacturer that doesn't work with AUS8 steel. Despite that, the price actually increased. The old micro recon 1 in AUS8 is being sold for $24.95 while the new micro recon 1 in 4034 is being sold for $27.19 on BladeHQ. Though it may not reflect actual price increase since BladeHQ can price whatever they want and the AUS8 might be cheaper because it's old stock.
When it comes to folder, i'm more concerned about CS being tone-deaf about requests for items i.e. non-coated blade and more EDC friendly sized knives in higher end steel that's proven by their competitors to sell very well(Para 2, Para 3, Griptilian, Kershaw Blur) as well as them making odd decision like making plastic clip or backlock with extra safety. The double-safe hunter and the 1911 is a good example. If you can't make a triad lock without compromising the quality, you might as well not make it at all, save the design till there's capability/capacity for that. 1911 is such a stupid, wasted effort. It could have been a great designed like the AK47.
Also the other concern is their move toward making less EDC stuff and prioritizing more weapons. Just look at CS's youtube channel for the past 3 months. It's axe, sword, more axe, Polearm, spear etc.
CS appears to starting spreading themselves too thin and I'm afraid they are going to start compromising for inferior material as demonstrated by this A2->4034 debacle.
