Differences in the lastic garden tools blade

Before using the kids garden tool set blade, we must determine a fact, the blade and the blade has a great difference.

The next is the fact that the number of cutting edge of each blade is relatively less. In many shops, car blade is triangular or rhombic. The number of plastic ice scraper the best combination of cutting edge (mechanical blade) and cutting edge strength (diamond blade) the possibility of convex triangular blade provides apparent in many garden tools are not enough cognition.

In twentieth Century 70 time, the best advice is to use large size, strong blade. Hard alloy used in that era is hard, but the toughness is not good enough. Plastic garden tools blade strength by its size (large blade = thick blade = high strength blade) to ensure. Three times a blade of garden tools the cutting edge length of at least more than cutting depth. Two things have changed at the same time. On the one hand, the average cutting depth for turning has been significantly reduced. A study carried out by the seco tools that plastic lever scrapers average cutting depth, the cutting is about 2.5~3mm. On the other hand, the fourth generation of hard alloy today has good toughness, but also its hardness (wear) higher. This means that for today's blade, the relationship between the cutting edge length and the cutting depth can change. The latest generation of blade geometry is suitable for the new situation.
