Knives are the oldest tool known to man. OK, maybe it’s fire, wheel, then knives. Well, maybe it’s pointed stick, then knives. You get the idea.
As old as knife technology may be, it’s still evolving. One of the latest evolutions is the Replacement Edge System or RES technology from TigerSharp. RES technology separates the cutting edge and blade into two separate parts.
By using a softer outer stainless steel blade support and a hardened, cryogenically treated surgical steel cutting edge, TigerSharp claims to have created a knife that can hold an edge up to four times longer than traditional blades.
What’s really cool about RES, thopugh is that the center part of the blade (made from GIN 5 stainless steel) is disposable. When you’ve worn the blade out, you can remove it and replace it with a new one without the use of any tools. TigerSharp claims the entire process takes only a few seconds and they have a video on their site to prove it.
We’re not sure how the RES system would hold up to heavy use and abuse — like, say, in the shop — but they do seem pretty handy for every day use. We could also see a great need for them if you hunt/fish and don’t want to stop to sharpen a blade for 20 minutes. TigerSharp has an entire line of RES knives in different patterns and styles to suit your particular slicing need.
Prices for the RES knives start at around $30, and replacement blades, both smooth and serated, go for around $10.
