@claycarmine12 No need for a video tutorial, ensure you have VRCFury and do the following after your avi is already on the screen:
Import your chosen toy. If it doesn't have SPS/TPS/DPS already, then you'll need to get that sorted out first (imo the easiest way to do this is to use the Configurator's 'tester' prefab and just change the mesh to something you like).
Open your avatar's hierarchy (the avatar's list on the left side). Follow this path: Armature>Hips>Spine>Chest>Left/Right Shoulder>Left/Right Arm>Elbow>Wrist.
Grab the prefab for your toy and click+drag it onto the 'Wrist' in order to attach it. It's now 'attached' to the wrist and will stick to it when the arm is moved.
Now that you have that part done, you'll want to have a Toggle for it.
Click the toy in the hierarchy (the one you attached to 'Wrist').
Look on the right side of the screen; this is your Inspector. Scroll to the bottom and click the "Add Component" button.
Type "Toggle" and select "Toggle (VRC Fury).
This is your basic 'switch' for things on your avatar. You'll make a few of these for different purposes. First, let's make one turn the toy on and off.
Menu Path: Here you'll create whatever path you want the button to be on. An example can be "Toy/Toggle", doing this will create a menu item on your radial called "Toy" and then another inside called "Toggle". You can make multiple submenu items this way, for example: "Toy/Toggle", "Toy/Size", "Toy/Material", etc.
Click "Add Action+" and select "Object Toggle". Click and drag the toy from the hierarchy (the left side one you attached to the wrist) into the box next to it. Now it will toggle the focused item on and off when selected.
If you want this setting to persist when you change maps/worlds with this avi, click the ellipses in the upper-right of the Toggle box and click "Saved Between Worlds".
Finally, if you want to have the item "drop" in the world, aka you want to place it somewhere static, make a new Toggle (follow the steps above) and, instead of selecting "Object Toggle", select "World Drop". Make sure you select the toy from the left and drag it into the box, just like you did with the toggle above. I suggest making the menu path similar to what you have for the above toggle, something like "Toy/Drop".
Feel free to experiment a little bit beyond that, but those are the basics.
