Welcome Kiba!
Unfortunately you just barely missed out on a good blade in the S5.
However...
There are Dogs here who purchased several and will probably end up selling some when time to pay for Waki's comes around. So, stay tuned and you may have a chance at an S5. As for survival blades, The debate will never end. Ultimately what I have seen is that your best option is not one knife but two. Whether it be in the form of a multi-tool or some other configuration is a matter of taste. Since joining the Yard my addiction for steel has afforded me many blades I love and would be willing to carry despite the weight factor. Ask these Dogs for combo pics of their favorite setups and you will get many links to previous threads on the subject. It is a popular topic.

To get a really good answer give us more details. What scenario will you find yourself using this knife in? Is there a type of steel you prefer? What size are you looking for? What kind of terrain will you be in? etc.
