and or a different tine gap as may be appropriate for different tissue or organ types fig5 7 depict a second presently preferred embodiment of the invention for ease of explanation the tool components are labeled with reference numbers corresponding to those used for the corresponding components in the first embodiment but incremented by 100 a description of the components is omitted except as necessary or desirable to differentiate this embodiment from the first embodiment in the embodiment illustrated in fig5 7 the tine supporting head 112 of the tool 110 is comprised of a base of each of the tine arrays 124 124 u2032 and a spacer structure 142 disposed therebetween the tine arrays and spacer are attached to one another and to the slotted distal end 116 of the shaft 222 of the tool main body 114 by for example welding as such the thickness of the spacer defines the gap between the tine arrays and the distance between the tine array outer faces defines the thickness of the tissue slice that can be prepared with the tool as shown in fig7 an advantage of this embodiment is that the tool need not include lateral shoulders to accommodate fasteners thus minimizing visual obstruction of the tissue specimen and the tissue slicing process the embodiment of fig5 7 also differs from the first embodiment in that the tines are uniformly distributed in each tine array the tines.
