Swiss Army Knife Icon in iPhone Style

This is a Swiss Army Knife icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,400 icons, all in the same style and quality.
A Swiss Army Knife is something that has many attachments on it, it's got a blade, but it's all inside of it that can be pushed outwards so you can see what it is. You'd have no idea what is in it unless it was yours. There's a knife, a cutting blade, and some other stuff in it!

Idea of Swiss Army Knife Icon by Eveline

We've received the idea on October 10, 2013 and created the icons on December 14, 2013

Please create these icons for camping/outdoors/recreation/adventure. (For the sake of completeness, I also mentioned the icons that are already present in the Icons8 library, so that other people can easily find these icons on this website) New icons:
- campfire
- forest
- camping tent (not the militairy tent, that one is for many people!)
- swiss army knife Swiss Army Knife icon ideas
- camping gas burner
- small axe
- creek / babbling brook 
- park bench 
- walking bridge (over a creek)
- waterfall
- tracks (not the ones from animals, but from people)   (not just two footsteps, but a path of footsteps disappearing into the horizon)
Existing icons:
​- trekking  - mountain biking - climbing - matches
- sleeping bag - log cabin - flashlight
- boots - backpack - tent

Thanks in advance.

This is a good example of the requested footsteps/tracks icon:
(but then in reverse, walking away from you instead of walking towards you)
