I bought some of these from Tryablade and I like them. I inquired about what the model number was for them thru Tryablade but unfortunately I never got a reply back. I'd really like to buy a 100 pack of these but I'm not sure which ones they are from a model / part number standpoint. I'd also like to get them at a lower cost if possible. If anyone could chime in that does know what model or part number these blades are I'd very much appreciate any information you can provide. Thanks
