Well it will give a wrench in inventory slot 4 I think didn't test.
function servercmdwrench(%client)
{
if(%client.isAdmin || %client.isSuperAdmin)
{
%client.player.tool[4] = nametoID(WrenchItem);
messageClient(%client, 'MsgItemPickup', '', 4, nametoID(WrenchItem));
bottomPrintAll("\c2" @ %client.name @ " \c6 has Claimed a Wrench!",5,3);
}
