what is the hardness rating (A)
707090
I don't know what the rating is but they didn't last long for my son. Maybe 3 weeks.

I am not understanding the nature of your question fully. At any rate I will attempt to answer to the best of my ability. It is a lil trick applying the wheels but you can find a good youtube video to assist you. That is what my son did to put the wheels on himself and he was 13 at the time. I hope I answered your question to satisfaction. All the best to you and Happy Safe Ripstik riding.

I carefully looked through the pouch and the knife, but can't see anywhere about the grade. I can only tell from my experiences that it is very solid and sharp. I bought the first one a while back and this is the second one (for my wife so she can have her own).

I honestly dont know what the hardness of the blade is, due to the fact that the blades are not of a high quality these details are often not given with the product. However if you want a rough estimate on how hard the blade material is from my experience with them they loose their edge quickly while cutting boxes and its not very easy to get a sharp edge on them like on my ANSA knife. I would say that its the same as the hardness on regular 440 stainless steel nothing special here.

I would think so since on the Knoop hardness scale glass&ceramic is 400-550, porcelain floor tile is 500-650, and granite is 550-650, tungsten carbide is 2000 and diamond 7000. diamondsure.com/materials.shtml Hope this helps. Charlie

They company states the blade is made from "the finest American stainless steel". They do not say what hardness it is.

I found a chart by searching 42hs4013a4, it seems to indicate 5mm, with a tolerance of 0 to -0.012.

Many differences - weight of A-1 is 30% more than Spyderco Schempp Rock and blade material in A-1 is laminated VG10 vs all VG10 for Spyderco. Blade thickness for A-1 is 1/4-inch, which is 2X thickness of Spyderco Schempp Rock blade. The A-1 blade is convex grind, which provides additional backbone to the cutting edge than the flat grind of the Spyderco. All in all, the A-1 blade would likely hold up to a lot more hard use than the Spyderco.

Sorry, I really don't know the rating. I am using one for my 700 watt microwave, and one for a toaster oven and haven't had any problems.

Joe, There is no documentation regarding the grade of aluminum. My guess is that it isn't "tool grade" aluminum.

I think I've seen these rated as 400 on the coarse side and 600 on the fine side. My estimation is that initially they act a bit coarser (say 200/300) but like most polycrystalline diamond abrasives the lose a lot of their aggressiveness after a little use. They do seem to last pretty well for their price. A year ago I bought 4 since they were so cheap and 3 are still in the box. The main defect is the metal abrasive plate tends to separate from the plastic substrate, so they are not good if a very flat surface is critical.

They don't rate the durometer rating on their product. However, after using it against other silicone products that do have ratings, I would say it is around a 20A shore hardness. It is very flexible, deals with undercuts well though you need to be careful with regards to tearing. It is a great beginner silicone until you "get the feel" for casting and start using specialized silicone for different project needs.

General rule is as little as gets the job done. Higher pressure causes wear & tear on parts. Start at 80 psi and adust air pressure for hardness of wood & countersink required.

im not sure of the grade, I can say it is higher than 308 stainless. its thickness is .020 or the same as 6 sheets of paper. , but is extremely resistant to bending. i have boiled water in mine over coals ( not open flame) many times. the bottom warped slightly , but no more than any pot of similar material and not enough to hinder the lid closing properly. i use mine as a wilderness kit and have been very pleased with it. slightly heavier than an aluminum but lasts much longer. hope this helped. if you have any more questions feel free to ask.

I can't tell you the exact hardness, but the finished product is about as hard as ordinary plastics.

I don't know, but it is a great, I have been filing a piece of 1/4" 3030 stainless steel, I got it because I thought I would break a few before I got the job done, 2 months later it works great, like the day I bought it
