It seems well coded, though there are some minor things :

- To disable buy and giving weapon, in this case, I would prefer to use keyvalue and letting the engine doing its job without any extra calls each time. And about the buy, I prefer to see the original message saying you can't buy. An example ( it's possible to use Ham_Spawn instead of pnf_keyvalue() :

    public plugin_precache() 
    { 
        new Entity;
        
        Entity = create_entity( "info_map_parameters" );
        DispatchKeyValue( Entity, "buying", "3" );
        DispatchSpawn( Entity );
        
        Entity = create_entity( "player_weaponstrip" );
        DispatchKeyValue( Entity, "targetname", "stripper" );
        DispatchSpawn( Entity );
        
        Entity = create_entity( "game_player_equip" );
        DispatchKeyValue( Entity, "weapon_knife", "1" );
        DispatchKeyValue( Entity, "targetname"  , "equipement" );
        DispatchSpawn( Entity );
        
        Entity = create_entity( "multi_manager" );
        DispatchKeyValue( Entity, "equipement", "0.5"   );
        DispatchKeyValue( Entity, "stripper"  , "0"     );
        DispatchKeyValue( Entity, "targetname", "game_playerspawn" );
        DispatchKeyValue( Entity, "spawnflags", "1"     );
        DispatchSpawn( Entity );
    } 
    
    public pfn_keyvalue( Entity ) 
    { 
        new ClassName[ 20 ];
        new KeyName  [ 16 ];
        new Value    [ 20 ];
        
        copy_keyvalue( ClassName, charsmax( ClassName ), KeyName, charsmax( KeyName ), Value, charsmax( Value ) );
        
        if ( equal( ClassName, "info_map_parameters" ) || equal( ClassName, "player_weaponstrip" ) || 
             equal( ClassName, "game_player_equip" )   || equal( ClassName, "func_buyzone" ) )
        { 
            remove_entity( Entity );
            return PLUGIN_HANDLED;
        }
        
        return PLUGIN_CONTINUE;
    }

- In fwdCmdStart(), you could use directly get_user_weapon() and no need to return FMRES_SUPERCEDE, FMRES_HANDLED is enough. But I would use the weapon's offsets ( m_flNextPrimaryAttack (46) / m_flNextSecondaryAttack (47) ) to block primary/secondary knife attack, it will be more efficient and you would not need to use FM_CmdStart.
- g_iMapType & TYPE_35HP || g_iMapType & TYPE_1HP ) ; you can do g_iMapType & ( TYPE_35HP | TYPE_1HP )
- Adding ML ?
- Never tried yet, but about the respawn stuff, it may interesting to use another condition than game_playerspawn if you use keyvalue, see http://twhl.co.za/wiki.php?id=1082

That's all.
