For Stainless Steel Knives (All Weather Tracker and River Knife)
It's important to understand that stainless is not stain-never. If you take care of it it will last for decades. Both the All Weather Tracker in CPM S30V and the River Knife in 440C require little maintenance. You can ensure your knife stays in top shape by always putting away dry after any adventure. It's best not to leave a knife in a wet sheath for prolonged periods of time. That said, these steels are superior in corrosion resistance and you need not worry about them when in the field or on the river.
When storing your knife for long periods of time, though not all that necessary with stainless steels, you can apply a very thin coat of oil to the blade for ultimate protection from oxidization. Apply and then wipe dry, it should not look wet after application.
Sharpen using any preferred method but always avoid mechanical sharpeners like belts or wheels that may generate friction or heat along the cutting edge. Heat can kill the temper easily along the fine edge. I sharpen all knives on a wet stone before they leave the shop.
All of my knife handles are either G10, Carbon Fiber or Micarta. The maintenance is all the same. I rough finish my handles to 150 grit for maximum grip in wet conditions. If you have a scratch or ding you want to remove you can simply gently hand sand with 150 grit paper. Avoid scratching the tang of the knife by sanding lengthwise if you are sanding near the tang.
If your handle starts to look "dry," has lost some of its vibrant color, or after sanding you need to apply oil or wax. I use mineral oil which can be purchased in any grocery store in the first aid section. Mineral oil is food safe and provides protection from the elements. Another great option is a product called "Axe Wax" from www.axewax.us. Axe Wax can be used on the blade as you would use an oil as well. Over time your handle material will become more and more impregnated with oils from use and require less care.
Kydex Sheath Care
Your sheath is made from Kydex which is a thermoplastic. The sheath was molded to your knife after being cooked to about 315 degrees. Your sheath should not ever be run through a dishwasher, especially a commercial washer, that reaches high temperatures. The best way to wash your sheath is using mildly warm water and soap by hand. Though it would take extreme circumstances, theoretically if your sheath was left on the dash of your vehicle on a 100 degree day in the hot sun it may reach temps high enough to become malleable again. Generally avoid extreme heat.
If your knife needs care beyond your comfort level please don't hesitate to contact me. We'll set up a spa day for your blade and get it back to top shape.
