good quality and is holding up well under average use.These blades are simply a nice product. They are made if heavy gauge steel hold a cutting edge and fit perfectly on my Sears Craftsman Mower. My lawn tractor uses three of these blades and the OEM Sears blades are $28.96 each plus shipping from Sears. This set of blades was 31.00 with the shipping. Unlike the Sears blades these are not marked as to which side faces the grass but if you look close the part number is only one side just like the Sears blades and that is ground side facing, just like the blades from Sears. At this price point, I'd say you can't go wrong. As a point of reference I live in the south where paved roads seem to be a luxury item in the rural areas and the driveways are covered with crushed stone which seems to get everywhere. and naturally cutting along the edges your mower blades are going to kick up stones no matter how careful you try to be. Hitting stones at 500 RPMs is going to dull a blade pretty quickly so you'd think and inexpensive blade would dull up pretty fast yet these are holding up.works goodFits my Craftsman 26HP mower. With Sears on the verge of bankruptcy, it's good to know I can still buy replacement blades for this mower.Better Then Going To Sears Store And Paying High Dollars Got These For More Then Haf The Price And Works Great good Even Cut to Grass Very happyI like them. They seem heavy duty. Hope they will not wear down as fast as the original ones did.The price is right, delivery is free with Prime and they are always exactly what we wanted.perfect fitment, good packaging.
