I have a hard time believing anyone is seriously cross shopping the two. People don't buy sebenzas just so they have a cutting tool. People buy sebenzas for the quality of design, materials, manufacturing, customer service, performance, exclusivity, and because its cool. Pretty much the same reason people buy Rolex's. Will a Timex or srm do the same job? Probably. Will they bring the same level of enjoyment to the owners? Maybe. Will someone who wants a sebenza be satisfied with a srm 710? Doubtful. Possible, but not likely. Not that its a bad knife, its just designed for a different market.
I buy Sebenzas to use as cutting tools. That is what they are. I also use a Rolex to tell time because that is what it is, a clock. I buy things I think will work well and last a long time.
I buy things to use. As much as I would like to I know I will not live forever. When I die a safe full of unused things will not make me less dead. I don't buy things with the intent of selling them.
I enjoy using the things I buy. If for whatever reason it breaks or wears out I will get it fixed or replaced. For me enjoying life is using the things I like.
