Useing kotor tool you can extract the Template Malaks lightsaber.
 this how BIFs->templates->g_w_lghtsbr06.uti.(note to view the uti you must have Roboius GFF Editor in the same folder as Kotor tool) go herefor all the Tools and Mods (
http://www.lucasforums.com/showthread.php?s=&threadid=122049) 
 you can extract g_w_lghtsbr06.uti with kotor tool or you can double click the file to view it in the GFF editor. 
 OK so you want to boost the attack damage of malaks saber look down list until you find the line PropertiesList. Select PropertiesList, right click and add[user-defined struct] now select highlite [user-defined struct] right click and add these nodes 
 ChanceAppear =100 
 CostTable [BYTE] =0
 CostValue [WORD] =0
 Param1 [BYTE] =0
 Param1Value [BYTE] =0
 PropertyName [WORD] =0
 Subtype [WORD] =0 
 now once thats done select 0 [user-defined struct:0]hit ctrl+C to copy then select PropertiesList again and hit ctrl+V to paste as many [user-defined struct:0] as you may need to leran what each node is for read the Item Format 
 document from bioware pay paticular attention to section 2.1.3 and 4.3 - 4.4.2 keep this doc open for refferance. 
 Use kotor tool for these next steps.
 Ok now to adjust the attack damage for Malaks saber. Useing kotor tool find [B]itempropdef.2da @ BIFs->2da.bif-> itempropdef.2da double click the file to open. 
 Here is a list of KotOR's item properties what you see is  
 (row label)=row# (name [xxx#])=the name as it is found in the dialog.tlk (lable)=property name (subtyperesref)=additional 2da that the property is related to *ie list (cost)=im not certain what this does :confused: (costtableresref)=value in iprp_costtable.2da 
 ok so now you should have the following files open 
 g_w_lghtsbr06.uti 
 itempropdef.2da
 and you should have atleast one subtree under PropertiesList in g_w_lghtsbr06.uti  
 So lets give malaks Saber more power first select property 11 and to the right we see that property is Damage and to the right of that is IPRP_DAMAGE TYPE and to the right of that under (costtableresref) is the # 4 now lets start. 
 1. ok now go down to the sub tree you made in malaks saber.Select the node PropertyName on your right there will be a box with the number 0 chang that to 11.
 now on your subtree it will read 
 PropertyName [WORD] =11 
 now open IPRP_DAMAGE TYPE.2da and select 12 which is Energy now back to the uti on the node Subtype and chage the value to 12
 now on your subtree it will read  
 PropertyName [WORD] =11
 Subtype [WORD] =12 
 now that subtree is a property which would read ingame as Damage energy(there is no chage to the saber yet) 
 now go back to itempropdef.2da and highlite 11 again,look to the right and under (costtableresref) you see the value is 4,again back to the subtree you created and select node CostTable and change the value to 4.like this 
 CostTable [BYTE] =4 
 now open iprp_costtable.2da and select row 4 which we see is IPRP_DAMAGECOST now open IPRP_DAMAGECOST.2da. here you will see a list from 0-10 each represents the amount of damage you can add. so lets give the Saber 2d6 damage which is 10
 again back to the subtree you created and select node CostValue
 and change that to 10.like this 
 CostValue [WORD] =10
 so now you should have a subtree that looks like this 
 ChanceAppear [BYTE] =100 
 CostTable [BYTE] =4
 CostValue [WORD] =10
 Param1 [BYTE] =0
 Param1Value [BYTE] =0
 PropertyName [WORD] =11
 Subtype [WORD] =12 
 now save as g_w_lghtsbr06.uti .Done now place the file in your override folder defualt 
 C:\Program Files\LucasArts\SWKotOR\Override 
 to access the saber ingame you do it the same way as normal in consol "giveitem g_w_lghtsbr06" without the quotes 
 now when you select malaks saber it will have an energy damage of 4-28. you can reapeat this proccess to add more energy damage or pritty much anything you want that is in the itempropdef.2da . 
 here is the sample file i made with this little tutorial
