## Questions & Answers

**Q: Are you all sure this is not a knock-off?  $260 saw for $115 makes me wonder.**
A: I see Amazon is claiming it's knocked down from $256.95.
When or if it ever really sold for that much, I don't know.

I suspect that if it did, it was back when the 500mm was the worlds largest folding saw? They could charge a premium for that distinction.
Now that the 650mm is out (for about $300), this one loses that honor and the price drops.

Just my thoughts though.

Oh, here you go:
https://camelcamelcamel.com/Silky-Professional-KatanaBoy-Folding-403-50/product/B002GKB5PQ
Amazon did list it for $256.95 when the listing was new. It looks like the price dropped dramatically after a day or so. Maybe that was the intention? That way they could honestly(?) say it's discounted from that price?

**Q: what is reasonable set???**
A: SET is the distance from each tooth from left to right.  NO SET would give a smooth cut but be very difficult to use.  Some SET makes the strokes easier because you will have a little air space in the cut making the push/pull easier. 
(the previous answer makes no sense)

**Q: Is this the Katanaboy 500??**
A: Yes - the "500" denotes the length of the blade, 500mm.

**Q: Does this come with the carry bag?.**
A: The full katana boy saw came with carry bag.  When I buy a replacement saw blade, it didn't come with a carry bag.

年金生活になり植木の剪定に毎年10万も払うのが大変になってきたので、背の高い木を切るために購入しました。 68歳、女の私でも、太めの木を切ることができて嬉しいです。
