Maintenance

This is a very easy, effective maintenance. Please make a strapping board by yourself, seeing the procedure. When you use this board, your knife sharpens for 2-3 years. Please send Japan your knife when not really cutting. ROCKSTEAD is reground it free of charge.However, the shipping back charge is your load.

  • Denim (clothe of jeans) is fixed to a handy board with the pushpin. Please wrap it hard so as not to loosen.
  • Becouse the tension is given to denim, it is strongly stretched. When denim loosens, it is not easy to strap.
  • We are using the liquid metal polish (brand name PIKAL of Japan). PIKAL is cheap. A similar commodify might be sold to the hardware shop in your country.
  • PIKAL is spread on the borad that you prepared. PIKAL is a commodity used to polish the candlestick etc.
  • PIKAL is thinly extended by using your finger.
  • You paint it so that there is no paint irregularity even as for the edge of the board.
  • In initial, this metallic polish infiltrates denim. Please sometimes add PIKAL after you use it several times.
  • When it is insufficient, you have to add and spread it.
  • Please dry it for a while when you finish painting PIKAL. PIKAL adheres to the blade when this is used in a wet state. This is not so effective.
  • Please do the strapping 2-3 times after you use the knife. Please refer to the photograph in the strapping direction.
  • Please strap it in carefulness. Denim is cut when moving it in the direction of the tip of the blade.
  • The blade is changed to the counter direction. When you change the blade direction, please separate it from the board. Your knife blade can be prevented from dulling.
  • Only strap it 2-3 times to the same direction. The sharpness of your knife will be restored.

Re-grinding

This is a sand paper retainer of ROCKSTEAD. We use the sandpaper of #2,000 or more large number (grain degree).

  • COMP2 is composed of apparatus and a rubber board. So as not to rust, apparatus is made of the stainless steel and the aluminum board.
  • This wedge roller pulls the sandpaper strongly gripping it. When the screw knob on the other side is turned, the power to pull is produced.
  • This wedge roller is a fixed side. When this screw is turned, the wedge roller on the other side pulls the sandpaper.
  • First of all, the sandpaper is inserted in a fixed side. Please use the sandpaper more large number than #2,000 (use smaller grain degree).
  • Please bite the sandpaper firmly pushing up the wedge roller on a fixed side by the finger.
  • The sandpaper is led to the other side. Please be careful that the sandpaper doesn't come off from the wedge roller on a fixed side.
  • The edge of the sandpaper is inserted between wedge rollers here.
  • The screw on the other side is turned while pushing up the wedge roller by your finger and the tension is given to the sandpaper.
  • This photograph is a state before giving the sandpaper the tension.
  • The tension is given to the sandpaper when you turn the screw. At that time, I recommend a left wedge roller to be supported by your left hand.
  • A left wedge roller is shown in this photograph, that is pushed by the screw.
  • The surface smoothes very much when the tension is given to the sandpaper. The preparation is completed by this.
  • Please paint oil on the sandpaper and grind your knife. Please do no push the knife in the direction on the tip of the blade. There is a possibility of cutting the sandpaper.
  • Please paint oil on the sandpaper and grind your knife. Please do no push the knife in the direction on the tip of the blade. There is a possibility of cutting the sandpaper.
