Four shapes are available. Please choose your shape from the drop down menu (#2,#3,#5,#6) tungsten carbide trimming/chattering tools, designed by Master Potter Hsin-Chuen Lin.These tools are designed with Tungsten carbide and stainless steel handle. They can maintain sharp cutting edges much longer, clean up easier and rust free.Caution:The tools are stainless steel handles brazed with tungsten carbide blades. Although it can maintain a sharp cutting edge longer, Tungsten carbide is not related to steel, nor is it flexible or bendable in the fingers. Do not try to bend the end to see how strong it is.Tungsten carbide is a very hard, dense material (ranking about 9 on Mohs scale). It is somewhat as brittle as fired ceramics. One must take care to keep them from bumping each other, falls, or being jumbled in a tool box when traveling.Resharpening instruction:The blades stay sharp for months. If needed, using a fine diamond file sharpen the inner side of the tools. The outside part of the tools have already beveled. By filing the inner part of the tools you should be able to make the tools sharp again.Please watch the resharpening video here:https://m.youtube.com/watch?v=Qil2vIoQq2oPlease watch the video on how to use the tools for trimming and creating chattering texture.https://www.youtube.com/watch?v=tgrq_E090EAhttps://www.youtube.com/watch?v=sNoTUJTO2Ckhttps://www.youtube.com/watch?v=oLNpVPI22VQhttps://m.youtube.com/watch?v=qmiCCh1NMvETo watch more of the throwing videos, please visit my Youtube channel:http://www.youtube.com/user/hsinchuenFor more information,please visit:http://hsinchuen.wixsite.com/mypots/hsintoolswww.mypots.net
