All beautiful, all good !!

Its stainless steel blade 85mm (I measured) is reinforced and partially serrated. It is quite reliable, and more than 8 on the classic Opinel intended for use less "physical".
Good handle bi-material, efficient and easy on the hand. His grip, the orange part, also allows users to view the beautifully well.
The whistle is not a gadget. It is strident and efficient.

Depending on your activity, sailing, climbing or caving in particular, I advise you to bring a reliable and sufficiently long strap that you slip into a pants from your example. This can you "save the day" ...

In short, very good product, strong, smart, and even intelligent, for a price which is not ruinous.

Good adventures, outdoor! ...
