How to make, where to buy or retune, fine-tune 5-10-15-20 kHz band tuning forks (quartz or ceramic) ?

Thanks for response to my previous request. Followed each reply and still don't know how to make kHz tuning fork (as an electronic component). Queried Wikipedia for tuning fork.

- crystals in MHz frequency band avaliable only.

- binary counters

by Don Lancaster - Our lowest frequencies are 28.8 kHz, 108 kHz, 153.6 kHz, 250 kHz, 256 kHz, 307.2 kHz, 326.4 kHz plus hundreds of higher frequencies.

by whit.... For wristwatches, a tuning-fork is used, and one can micromachine it ..... from quartz and laser-trim its weighted tines for frequency and couple to it using the quartz material's piezoelectric properties. The typical resonators used for 5 kHz are tuning forks and guitar strings, or they aren't mechanical at all...

LXO OSCILLATOR

10 kHz to 2.1 MHz Low Power Crystal Oscillator but picture comes from 2.0 MHzCrystal Oscillator clock oscillator only The characteristics of the 32.768 kHz model are presented in this data sheet. Are data sheets for lower frequencies also avaliable ?

Catalog Section D - Crystals and Oscillators unfortunately, frequency range is MHz notr kHz Quartz Crystals - ECS-31 Series is for kHz range p- lowest frequency is

32.000 32.768kHz Tuning Fork Crystals lowest frequency offered non-programmable oscillator is for 20.000 kHz.

So is there no chance to make, order a non-programmable oscillator for kHz band

5 kHz, 10 kHz or the like to test wireless energy transfer by Tesla ?

Mayby a small, home arranged lab could micromachine or laser-trim a tuning fork to meet my needs or should I give up the idea of ordering samples of tunning forks with frequenciec in kHz band of my interest.
