Step 1: Compare figures in pairs instead of rotating all seven at once.
Take figure 1 as a reference. Its head is oval, tilted diagonally, with the handle coming out of the lower end of the oval and continuing in roughly the same diagonal direction.
Step 2: Check figures 4, 5 and 6 against figure 1.
Figure 4 is simply figure 1 turned to a steeper angle, figure 5 is figure 1 turned so the oval lies flat, and figure 6 is figure 1 turned so the handle points up and to the left instead of down and to the right. In every one of these three, the head sits on the same side relative to the handle as it does in figure 1, only the amount of turning is different. So 1, 4, 5 and 6 form one matching group, related purely by rotation.
Step 3: Check figures 2, 3 and 7 against figure 1.
In figure 2, the oval head sits on the side of the handle opposite to where it sits in figure 1, once both are turned to point the same way. The same swap shows up in figure 3 and again in figure 7, in each of these three, the head has flipped to the other side of the handle, which a plain rotation cannot produce.
Step 4: Conclude which figures are the mismatches.
A shape and its mirror image always differ in exactly this way, the handedness flips even though the outline looks similar at a glance. Since 2, 3 and 7 all show this flipped handedness compared to the group of 1, 4, 5, 6, they are the three figures that do not belong with the rest.
Final Answer:
Figures 2, 3 and 7 are the three odd ones out.
\[ \boxed{2,\ 3,\ 7} \]
