This is the same production and distribution path used by other CPM steels like S45VN, S30V, S35VN, 20CV, S90V, etc. So the steel will eventually have full availability through steel suppliers and to knife companies.Pros Cons How to Choose Between the S30V and S90V Edge retention Toughness Ease of sharpening Intention of Use Price What Makes a Good Quality Knife? Final Thoughts S90V steel knives offer better edge retention than S30V steel knives meaning you can use them for a long time without sharpening.I own s30v, m4, and s90v. My dedicated skinning knife is in s90v due to edge retention. My overall outdoors/hunting knife is s30v because its less rigid than s90v but still holds its edge well (I accidentally snapped the edge of s90v last year because of its extra strength/hardness).If the S90V data sheet is any guide, the S90V wear resistance and toughness they've used for the chart in the S35VN data sheet are for S90V at 58 HRC. At the actual hardnesses the steels are run in cutlery applications (58-59.5 for S30V, ~61 for S90V), then yeah, S30V will be noticeably tougher.Most industries use structural steel beams to build their structures due to their strength, ease of construction and durability. The cost of structural steel beams varies depending on their size and shape. | Cjcehbuwuxxym (article) | Mzajrv.
