In the Dedicated Server on Sakhal the Whetstones RARELY SPAWN.

But you many to build because otherwise you cannot find enough tools.

The TYPES.XML for WHETSTONES is this:

<type name="Whetstone">

    <nominal>30</nominal>
    <lifetime>28800</lifetime>
    <restock>0</restock>
    <min>25</min>
    <quantmin>-1</quantmin>
    <quantmax>-1</quantmax>
    <cost>100</cost>
    <flags count_in_cargo="0" count_in_hoarder="0" count_in_map="1" count_in_player="0" crafted="0" deloot="0"/>
    <category name="tools"/>
    <tag name="shelves"/>
    <usage name="Farm"/>
</type>

The main problem is the:
<tag name="shelves"/>

->There are not enough shelves in FARM locations for WHETSTONES this in DayZ.
->Whetstones often spawn at the out house, which seems to be treated like a "shelf"

Please remove for type WHETSTONE the tag for SHELVES or make them spawn in other places too, like INDUSTRIAL. Thanks
