These templates have hands that can be repositioned or replaced.
For the hands where the fingers are visible there is a mask object (green) that can be used to trim the handle of anything that the hand needs to hold. You may need to ungroup the image objects so that you can select just the green mask object to use it for trimming.
Once you have trimmed the handle, or if the hand doesn't need to hold anything, the mask can be deleted.
Regarding the Two Arms in Armour images that have a lot of variations:
The names of some of the files are almost certainly wrong for blazonry, there are 16 subtle variations on the two arms, one in mail and the other in armour and I'm not quite able to keep all the variations straight in my head.
It should also be noted that despite the large number of variation images, heraldically, they should largely be considered one charge. The differences should be considered largely aesthetic because the goal of heraldry is to produce symbols that are readily identifiable at a distance, the minor differences fail this test. Just choose the version you like and use the correct dexter/sinister hand combination.
